On day 16 of the production, after several takes of a fight scene, the actors staged a take to make it look like one of the actors actually got hit in the face. The reaction shots of the extras are used in the final cut of the film.
On day 10 of the production, one of the car kino-flo interior lights did not work. The Claire grip team was able to create a make-shift light using a flashlight, a diffusion filter, a gel, a grip clip and a stinger box. The scene made it into the final cut of the film.
