Conception Kuiil was created as an original character for
The Mandalorian, a live-action
Star Wars television series that debuted on the
Disney+ streaming service on November 12, 2019. Concept art was prepared for the character during pre-production, including an image by Christian Alzmann of Kuiil and the Mandalorian riding blurrgs alongside each other, and another by Jama Jurabaev of Kuiil and the Mandalorian at his moisture farm. Ugnaughts had first appeared in
The Empire Strikes Back (1980) as workers on
Cloud City, as well as various
Star Wars novels. The first footage of Kuiil was shown in a trailer for
The Mandalorian released on November 6, 2019, less than a week before the show debuted. The trailer included a brief clip of Kuiil, as well as a small amount of dialogue from the forthcoming show, in which he said he has never met a Mandalorian before but has heard stories about them.
Portrayals performed the voice of Kuiil. The voice of Kuiil was performed by veteran actor
Nick Nolte. In a 2011 interview, eight years before the release of
The Mandalorian, Nolte said he would have been "kind of a goofy
Star Wars guy" if he had been cast. Nolte's casting was officially announced on November 30, 2018, though the character he would be portraying was not initially revealed. He was the third cast member publicly confirmed for the series, after
Pedro Pascal and
Gina Carano. calling it "the most amazing job of my life". Among the dialogue Rosas recited during her audition was Kuiil's signature line, "I have spoken", and she believed the producers studied her delivery of this line to gauge her understanding of the character. Rosas felt an immediate connection with the character based on her own life experiences, saying: "I know what it is to fight for your freedom." Rosas also said she related to the character's wise and thoughtful personality due to her regular practice of

core stability. Kuiil's eyes are not part of the mask, and instead, Rosas' actual eyes with contacts are visible. Unlike some costumes Rosas has worn in past performances, she was able to see clearly while filming, but it was occasionally difficult to breathe because her mouth was far back within the mask. She occasionally needed to ask crew members to open the mouth of the mask for her between takes so she could breathe more freely.
Filming Before scenes involving Kuiil were filmed, the cast and crew of
The Mandalorian held private rehearsals with actress Misty Rosas in which she did not wear the costume.
Jon Favreau, creator and
showrunner of the series, attended these rehearsals, in which they would attempt to determine the rhythm and timing of each scene. Rosas called the rehearsals "the most nerve-wracking for me". Nick Nolte recorded dialogue for Kuiil before the character's live-action scenes were filmed, providing multiple takes with different performances and vocal inclinations for the crew to choose from. Rosas felt Nolte's voice work for Kuiil was "beautiful". Once the dialogue was ready, Rosas and other members of the crew, including the episode's director, would listen to the various recordings, arrange the chosen recordings, and prepare to shoot the scenes. Rosas and the puppeteers prepared extensively to ensure their efforts were coordinated, and during filming, she would provide them a non-verbal signal to indicate when she was about to act out a line of dialogue so they could operate the mask. Occasionally the puppeteers would miss her signals, particularly during scenes that were dimly lit, One full day of filming the episode focused upon Kuiil riding the blurrg, a process Rosas described as "intense" due to the amount of time she spent on the fake creature and the speeds at which it was made to appear to run. The process was made further challenging because she was carrying the heavy animatronic Child prop throughout the scenes, and she occasionally needed breaks between takes. Rosas said: "My legs are not exactly long, so I was squeezing for dear life and holding the baby." However, Rosas was able to place the weight of her animatronics-filled backpack on the saddle of the blurrg while filming the scenes, which helped relieve pressure on her shoulders, neck, and back. While the closing credits music for
The Mandalorian is usually fairly upbeat, a slower and sadder composition was used for "Chapter 7: The Reckoning" because the credits immediately followed Kuiil's death in the final scene. ==Themes==
