Deliberate mistake: In the scene where Maya is looking for Rodney at the party and he scampers off into the bathroom, he miraculously climbs on top of a toilet in a matter of seconds (which isn't actually shown). There is no way a guinea pig could do this.
Dr. Dolittle (1998)
1 deliberate mistake - chronological order
Directed by: Betty Thomas
Starring: Eddie Murphy, Oliver Platt, Peter Boyle, Ossie Davis
Continuity mistake: When John returns from the hospital, Maya is sitting down, then stands up. The camera then goes onto John, then back to Maya, then she stands up again.
Lucky: A little girl once called me "Please mommy, not him."
Trivia: The scene where Dr Dolittle awakes to find the guinea pig in the bed with him looks like an homage to the horse's head scene in The Godfather. The way he screams, and the way the camera cuts to an external shot, is an exact copy.
Question: Why did Geno break Mark's nose at the end during the party?
Answer: Geno deliberately broke Mark's nose during the party after Mark made a snide remark. After the party, when Mark suggested a way to have John committed and still get their money, Geno had enough of Mark's ignorance and punched him in the nose again to add further insult to injury.
