Development and funding Shiva Baby is an expansion of writer-director
Emma Seligman's 2018 short film of the same title, which she had made as her thesis project while studying film at
New York University Tisch School of the Arts (NYU). The title refers both to Danielle and to the baby brought to the , Rose. Seligman said that she felt there was room to expand on the short from early on, but needed motivation from lead actress
Rachel Sennott to start working on a feature; the feature film entered production just before the short premiered at the
2018 South by Southwest (SXSW) film festival. Despite the short being accepted to SXSW, giving Seligman confidence, nobody there was interested in making a low-budget feature. Seligman then approached Katie Schiller, who she said was "the best producer in [their graduating class]", at Sennott's encouragement. While developing the feature, Seligman re-watched
Gia Coppola's film
Palo Alto, saying that she had "never seen a film so accurately portray the suffocating and debilitating nature of young female insecurities" like it. Seligman was also inspired by
Trey Edward Shults's
Krisha and how its location was used for storytelling, which led to Seligman viewing
Shiva Baby through a similar psychological thriller lens. Other inspiration came from the
Coen brothers,
Joey Soloway's
Transparent,
John Cassavetes, and
Mike Nichols. The costume design of the film was based on outfits worn at Seligman's family had attended. Seligman said that financing
Shiva Baby was "probably the hardest thing" she and the producers would do; she sought funding for the feature for a year and received some offers from organizations that requested more creative control over the film in return, which she was unwilling to give. The production also faced setback when Seligman had to return to Canada after finishing the short when her visa expired. Filmmaker
Amanda Kramer, a friend of Seligman, put her in contact with Rhianon Jones of Neon Heart Productions, who became an
executive producer; more investors became interested with Jones attached. Most of the financing came from outside funding and independent funding from people the production team knew. Seligman told
Women and Hollywood that using primarily one location was also a financial decision.
Shiva Babys budget was around $200,000. Producer Kieran Altmann managed to secure some funding from his parents, Fiona and Martin Altmann, who are credited as executive producers. He said that the competitive filmmaking market in New York helped them work with a small budget, as they could negotiate large discounts on gear rental. The crew were also friends of the producers, and most took a cut in their usual rate, while editor Hanna Park was Seligman's roommate.
Themes The short film had been based on a fictional scenario combining Seligman's "uncomfortable and funny" experience of , and the community of women she knew who were
sugar babies at NYU. When it came to expanding the story to a feature, she chose to also draw on her own
bisexuality; the desire to showcase more of the character of Danielle and her sexuality is a reason Seligman chose to make the feature. Seligman said that "if no one watches this movie except for some young bisexual women who feel seen, then I feel like I've done my job". The character of Danielle is described as relatable; she is the film's "way in" and the other characters are all seen through her eyes. Seligman was also interested in exploring Max and Kim's relationship, and Debbie and Danielle's mother–daughter relationship further, and in expanding on the central theme of Danielle finding her self-worth through sexual autonomy but "realizing that's not as powerful as she thinks it is".
Variety noted that themes of empowered young women were present in several screenplays in the same season; features editor Malina Saval wrote that
Shiva Baby shows through Danielle how a "pressure to be perfect manifests itself in women long before marriage and kids come into focus" and explores how the power of sex is only limited. Karina Solórzano for the
Los Cabos International Film Festival wrote that
Shiva Baby has "the same elements as some of
Woody Allen's most popular films – including the Jewish family and multiple lovers – but Seligman has her own vision and offers something different", and that it "follows the contrarian path promoted by [...]
Disobedience, [but] this is not the central point of the plot; Seligman does not treat the [queer] protagonists as exceptional or disobedient". Solórzano also compared the themes of youth to those of
Booksmart, and the tension to that of
Uncut Gems, and discussed the relevance of other themes in
Shiva Baby, including Danielle's insecurities; the cultural and religious conflicts surrounding Danielle's sexuality; complex female relationships; and the honesty that comes with family gatherings.
Casting Writer-director Seligman became aware of lead actress Sennott at NYU when Sennott was acting in other students' thesis films and making comedy sketches. Thinking that she looked "like someone [Seligman] would run into at a family event", Seligman cast Sennott in their own thesis film, the
Shiva Baby short. Sennott was kept on as Danielle when Seligman began expanding
Shiva Baby into a feature-length film; they had formed a collaborative bond and Seligman "never even thought about casting someone else", though, unlike her character, Sennott is neither queer nor Jewish. When media began criticizing
Jewface, Sennott as Danielle was frequently mentioned. She worked with Seligman to develop the character over the two years of production from the beginning of the short film to the feature, and read all of Seligman's screenplay drafts. Some of the film's potential financiers asked the producers to consider replacing Sennott with a bigger name star. Besides Sennott, the first actor to be cast was
Molly Gordon, who was cast as Danielle's love interest, Maya, without a chemistry read with Sennott; they only met the day before filming began. Seligman says she experienced
impostor syndrome working with the cast, especially after holding a rehearsal for a scene between Danielle and Maya but not being able to make it work. After Gordon,
Dianna Agron was cast as Kim. Agron was in Israel when she was sent the script, and met with Seligman in New York shortly after returning. Seligman said that, as a Jewish actress, Agron was excited to "finally" be in a Jewish film, despite playing the only character who is not Jewish. Through conversation with Agron, lines were added alluding to her character having Jewish heritage. Producer Lizzie Shapiro told
Ynet that Agron "brought to the role a different dynamic of what it means to be a Jew who looks like [she does]". Commenters have said that Agron's casting is an example of
intertextuality and "a bit of an inside joke". Danny Deferrari was the last actor to be cast, accepting the role of Max a few days before shooting began. Casting had been challenging; the film focuses on both queer and Jewish culture, so Seligman and the producers wanted to find actors who would "feel authentic to the material". Seligman felt it was important to cast Jewish actors but was open to other people if they seemed perfect for the role. They also discussed authentic queer representation with
The Hindu, calling it a "trickier issue"; having spoken with actors who are not
out, Seligman said that "for everyone on screen playing a queer character to be out and proud and talking about their sexuality [...] is a lot to ask of someone." Casting director Kate Geller went to the Jewish theatre community in New York for most of the cast. Due to the low budget, they looked to only cast actors based in New York City, with the exception of
Fred Melamed, whom the production flew out from Los Angeles. Melamed had accepted the role of Joel based on reading the script alone. Unbeknownst to Seligman, several cast members already knew each other, such as Melamed and
Polly Draper (who plays his wife Debbie), who were friends from the
Yale School of Drama; they used this as an advantage on set, though Draper had originally been sought to play a different role in the film. The production had been looking for a Jewish actress to play Debbie, but Seligman said that Draper "put a spell on [them] and [they] had to say yes." Seligman's own mother also wanted Draper to play the mother character in the film. Draper improvised on-set for her character a lot, as well as adding a mother's perspective, though the production did not have time for full improvisation.
Filming Shiva Baby was filmed over 16 days in August 2019 at an
Airbnb in
Flatbush, Brooklyn. Seligman chose the house on because of its dark wood interior and stained-glass windows providing a
Yentl-like glow. The shoot was initially planned for summer 2018, which was postponed to 2019; Seligman then wanted to push it again, to 2020, to have more time to raise money, but Sennott "set a timebomb". The film mostly
takes place in one location during one day. After scouting the house, Seligman built a model of the
first floor out of
Lego and used this to plan shots. They said that some of the main struggles related to
continuity, particularly working with actors who were not always available at the same time. The production had only "two days when [they] had the entire [principal] six-person cast together at the same time". Another struggle was the baby playing Rose, who would not stop crying; Seligman said this was a "learning experience" that caused them to rework some scenes to fit in a crying baby. The opening scene, set before the at Max's apartment, was filmed on the last day. Seligman, with a largely female cast and crew, felt prepared for this and other scenes involving intimacy, but discovered during filming that the scenes were more vulnerable and required more sensitivity.
Director of photography Maria Rusche used an
Arri Alexa XT camera to shoot in
fullscreen 2K resolution and
Apple ProRes 4444 format, with
Kowa anamorphic lenses as well as a 10:1
Cooke Cinetal
zoom lens. About half of the film was shot
handheld. Seligman and Rusche initially considered shooting
Shiva Baby like a
romantic comedy, but "the anxiety hook was what [they] found to set the tone for most of the process". Rusche discussed her equipment choices with
IndieWires Chris O'Falt, explaining that to capture the
claustrophobia and anxiety in the film in the way they wanted, they needed to have Danielle surrounded by people but still allow the principal cast to play off each other. To achieve this, Rusche decided to use an anamorphic lens so that multiple characters can remain in shot together, through the wider
field of view, while still being distinguished from background characters thanks to the lens's depth. They also wanted to utilize natural
image distortion to emphasize Danielle's anxiety; Rusche said the effect of the Kowa lenses "helped make it feel like the walls could literally cave in on her" and had "a good balance of edge distortion without falling apart or losing too much sharpness at the edges".
Music Seligman was uncertain if they wanted to use a
score for the film when going into production, as they were aiming for
realism, but chose to do so to divert focus from background chatter and represent Danielle's emotions. Seligman wanted it to have strings to reflect
Klezmer music, without being overpowering, a "sweet spot" that they said composer Ariel Marx achieved. Marx also suggested adding the score to some scenes it had not originally been intended, making them more stressful. As well as composing, Marx performed strings, while Sam Mazur contributed percussion. The score received positive reviews. Stephen Saito for
Moveable Fest described the score as Marx's version of the
Jaws theme.
IndieWires Jude Dry wrote that the "tense string score ratchets up the tension, though this technique loses its bite after a few too many uses", while Katie Rife of
The A.V. Club praised it, likening it to the work of
Harry Manfredini. Andrew Parker for
The GATE also touched on the score's
horror-like qualities, saying it worked well for its contribution to the claustrophobic storytelling.
The Film Stage listed it as one of the best scores or soundtracks of 2021. ==Release and marketing==
