The movie contains a spoof of Saving Private Ryan, where Manny is hit by a geyser and temporarily loses his hearing. Incidentally, the German voice for Manny, Arne Elsholtz, also synchronizes Tom Hanks, who also stars in that movie, which creates an inside joke by happenstance in the German version.

In the trivia game on the DVD, one of the questions asks how many Possums were seen in the movie. The accepted answer is 2, but the correct answer would be 3: Crash and Eddie's mother is shown in one of Ellie's flashbacks.
