R.L. Osborn and Martin Apariljo perform BMX feats throughout much of the end credits.
The end credits contain five "trainee" credits that are censored. According to co-writer Sam Bernard on the behind-the-scenes commentary, the reason why the job titles of the trainees are covered up is because the Writers Guild of America wouldn't let the crew put them in. Originally, "Trainee script writer" was written, but it was pulled at the last minute, worrying they could be fined.
