The three chapters of the film were originally produced and released theatrically as three animated short films. The first installment,
Everything Will Be OK, was released in 2006 and won the 2007
Sundance Film Festival Grand Prize for Short Film. Despite the film's short running length,
Variety film critic Robert Koehler named
Everything Will Be OK one of the "Best Films of 2007". The film was extremely well received by critics, describing it as "essential viewing" and "simply one of the finest shorts produced over the past few years, be it animated or not".
The Boston Globe called the film a "masterpiece" with the
Boston Phoenix declaring Hertzfeldt a genius.
Everything Will Be OK advanced to the final round of voting for Best Animated Short Film at the 2007
Academy Awards, but did not make the final list of five nominees. Outside of theaters,
Everything Will Be OK was first released as a limited edition DVD "single" in 2007. The DVD featured an extensive "archive" of over 100 pages of deleted scenes, Hertzfeldt's production notes, sketches, and layouts, as well as a hidden
Easter egg that plays an alternate, narration-free version of the film to highlight the sound design. The second installment,
I Am So Proud of You, was released theatrically in 2008. It continued the dark and philosophical humor of the first film, seeing Bill's recovery haunted by the apparently genetic inevitability of his mental illness, the lack of control over his own fate, and the sudden death of a loved one. The short suggests "simultaneous" connections throughout time, through his strange family history, his childhood, the present, and his old age. For the first time, Hertzfeldt embarked on a solo tour with the film, presenting a special "Evening with Don Hertzfeldt" program in multiple cities.
I Am So Proud of You received similar critical praise and received 27 film festival awards, including the Grand Jury Prize at the
Florida Film Festival and the Golden Starfish at the
Hamptons Film Festival. Director
David Lowery wrote that the film is "as good a pick as any for film of the year... full of grand and complex thoughts about life and death and bodily fluids and years rapidly advancing, coming to ends and beginnings, back and forth, over and over, until one slips indistinguishably into the next". Chris Robinson, author and director of the
Ottawa International Animation Festival, described
I Am So Proud of You as a masterpiece. Following its theatrical release, a DVD "single" of
I Am So Proud of You was released in August 2009, featuring another extensive "archive" of production materials. The final chapter of the trilogy, ''It's Such a Beautiful Day'', was released in 2011, winning several awards, including a Special Jury Prize from the Hiroshima Animation Festival. In 2011 and 2012, Hertzfeldt again toured the United States and Canada to support the final chapter in another "Evening with Don Hertzfeldt" program. While this theatrical program presented all three of the short films together for the first time, it still presented them as individual shorts, not yet as a unified feature film. The final, unified feature film version, ''It's Such a Beautiful Day'', shared the same title as the third short film and had a limited theatrical release in 2012. It was nominated for Best Animated Feature Film by the
Los Angeles Film Critics Association.
iTunes, In 2021, the film was released on the

Re-release In 2024, ''It's Such a Beautiful Day'' was rereleased in theaters for the first time since 2012, paired with the release of Hertzfeldt's newest animated short film
