Continuity mistake: Scheck calls Nick and informs him the kids have a copy of the document on videotape, and they're headed uptown. During the following scenes, both Nick and Big Bob have medical adhesive tape on their cheeks (due to their earlier fight). In some shots Nick's cheek has two crisscrossed tape strips, but in other shots only a single strip of tape; the changes go back and forth. (01:03:20)
