Trivia / The Umbilical Brothers

• DVD Commentary: The commentary for Speedmouse has Shane and David frequently sidetracked or interrupted by the other characters from the show, and when they do provide behind-the-scenes information it's false. Several times, they claim that various imaginary props and characters were actually present in the theatre, but were digitally removed in post-production. At one point, they instead admit that a particular imaginary character really was just a voiceover, then claim that it was intended to be a visible CGI-animated character but all the earlier digital object removal broke the CGI budget.
