Soul to Squeeze is the first film ever to have a continuously changing aspect ratio throughout the entire film. It begins in a 4:3 aspect ratio and expands out to a 2.35:1 by the end.
During production, Michael Thomas Santos had to both lose weight and gain it back. This is because the character loses weight during the course of the film. But since the production had to shoot out of sequence, they had to shoot the scenes they missed the first time when he got back up to that missed scene's weight again.
