The film's title is taken from the blues song by Sonny Boy Williamson, "Fattening Frogs for Snakes". Singer Patti Smith apparently brought this song to the director's attention; in the end credits she receives "special thanks" for its use.
The license plate on Al's car is "2BNOT2B".
Even though Ron Perlman is billed on the cover/poster for this film, he is only in two scenes, and only one is a dialogue scene.
