Castling was shot in Mt. Pleasant, Michigan as part of the Broadcast and Cinematic Arts program at Central Michigan University. It is the final class project for nine seniors, who each took a crew position. Equipment was provided by the university, allowing the students to concentrate on making the film they wanted to see, rather than being limited by equipment. Businesses in town generously donated the use of their facility for use in the film, and so the entire project was produced on a shoestring budget totalling less than $100, for various props and the occassional food break.
The script, by Kris Moore, was written for a scriptwriting class in the Theatre and Interpretation department of Central Michigan University.
