The six friends who plan the bank robbery (Benny-Big Time, Erik, Derek, Jamie, K.C. and Kyle) were named after Maguire's six close friends from his younger years. The only bank teller seen (Yvonne) who is also pregnant, is named after Maguire's mother. The other two bank tellers (Annette and Maryann) mentioned in the movie were named after Maguire's aunts.

The closing credits include a person who had yet to be born: The bank teller "Yvonne" (played by Liat Roman) was actually pregnant during production. After "Jamie" takes a picture of her, he checks the display on his camera and the belly is featured in closeup. The filmmakers wanted to give this baby bump a credit in the movie, so they waited until Liam Roman was born and credited him as "Bump".

The version of 'Bank Roll' that played at various film festivals had music included in many of the scenes. The filmmakers removed all the music for DVD and video on demand sales, but bootleg copies of the festival version have been floating around.
