To more accurately portray a story of imprisonment, director Chris Tashima wanted to include images of the guard towers that were a prominent historical element of the relocation centers. However, constructing a 40-foot tower was proving to be too expensive. To save time and resources, only the "Booth" section was fabricated, then raised on a construction scissor-lift, to give it the proper height for filming. The lift was replaced with CGI "Legs" in post-production. Also, at the suggestion of John Esaki, a 1/4-scale model was built. The model is featured in one shot in the film, and on the movie poster. The same model has also subsequently appeared in other films: Esaki's Stand Up for Justice (2004) and The Manzanar Fishing Club (2012).
