Deliberate mistake: In Antarctica when Charlie and Cam kiss, their tongues become froze together but this is impossible as it would take a freezing object for this to work.
Good Luck Chuck (2007)
1 deliberate mistake
Directed by: Mark Helfrich
Starring: Jessica Alba, Dan Fogler, Dane Cook, Sasha Pieterse, Troy Gentile, Connor Price, Mackenzie Mowat
Revealing mistake: When Jessica Alba is in the dentists room with the chipped tooth, it's very obvious she's wearing a set of false teeth over her teeth.
Cam Wexler: Shit! Shit shit shit... pardon my French.
Charlie: I speak a little French and that sounded like "shit."
Trivia: In the scene where Chuck and Stu are playing frisbee, the hat that Chuck is wearing is the Super Club hat from Dane Cook's previous film, Employee of the Month.
