Nathan Jackson and Michael Gilmore commented that they were interested in doing a film about the series on the Li'l Homer Season 2 DVD in a bonus feature. Not long after, the plot, director & co-director, producer, and other small details were announced at the S89 Expo on August 20, 2011. On April 24, 2012, Bongo Studios announced that it would be titled Li'l Homer: The Movie.
In June 2012, Nathan Jackson gave details about the film's plot: "The film's kind of going to touch on the themes and format from the series, but in a way we could not do in the series. It’s going to be a summer camp movie and, at its heart, it's about Homer and his friends going away from home and meeting this alien that is lost too and so they all end up forming this bond and it becomes this unique kind of adventure..." One of Jackson and Gilmore's intentions was to explore what aliens represent in film. Nathan Jackson said: "It's time to do a movie where you get to see what would really happen if an alien landed on Earth." Jackson said the inspiration for the movie came from watching E.T. The Extra-Terrestrial as a child.
For the alien, Jackson wanted to create something that had never been seen in film before. In order to achieve this, Nathan Jackson visited biologists Curtis Clark and David Moriarty in order to figure out what an extraterrestrial lifeform might look like. The alien (codenamed EBE-1) was designed via input from artists Joschua Knuppe and C.M. Kosemen. The idea that the alien not speak came very early on, to show that its bond with the characters went beyond words. Jackson described the film as a "boy and his dog" story, with the alien in the role of the dog.
The cast and crew from the series will return, including Nathan Jackson as director and co-writer with Michael Gilmore. Initially, Jackson was directing the film alone, but by February 2015, Sian Wilson had joined him as a co-director and writer. According to the report, Wilson, who was a writer on the series, joined Jackson following his request to strengthen "the director's bench" to ensure that the film is completed in a timely manner. At the S89 Expo it was announced that Hanna Spearitt, Sigourney Weaver and J.K Simmons had joined the cast of the film.
The film's main antagonist, Agent Carter, was described by Wilson as "the most formidable villain yet,". Jackson and Gilmore wanted her and her team to stand apart from the bullies and petty criminals that characterized the series. Jackson reasoned: "This is a movie, and you need a convincing antagonist for a movie. Where can you go for a movie? You have to go bigger, with more far-reaching plans."
In June 2015, it was announced that the majority of the cast had been revised. Of the original cast, only the cast from the series retained their roles in the film. It was revealed that Hanna Spearitt had been replaced by Olivia Yoxall, and Sigourney Weaver had been replaced by Bryce Dallas Howard. The three camp bullies, to be voiced by Neil Patrick Harris, Bill Hader and Judy Greer had been cut altogether and replaced by a single character named Johnny, voiced by Yuri Lowenthal. On the cast revisions, Jackson explained ""It was all about the changes to the script, really, it was really about the themes of the film, so that we could push the ideas we were trying to infer. Then everything else, all the other characters that supported that story came in and out and changed and evolved and through that evolution, some of those performers changed out of it." Dialogue was re-written in order to fit the new interpretations of the characters. In particular, an Alien reference was removed from the script, since it would not have fit with Bryce Dallas Howard's interpretation of Agent Carter.
