Deliberate mistake: When young Becca picks up the drawing that young Seth made, in the first shot, as she flips it over to look at it, you can faintly see the pen-marks through the paper, and they are not the same as in the following close-up shot, when we see the actual drawing. In the first shot, they seem to be a grouping of rectangular shapes, whereas in the second shot, it is obviously a large drawing of a penis. They had to use different pictures due to child labor laws that wouldn't permit the young actress from seeing the actual picture, and so a hand-double was used for the close-up shot. (00:17:15)
Superbad (2007)
1 deliberate mistake
Directed by: Greg Mottola
Starring: Seth Rogen, Jonah Hill, Bill Hader, Michael Cera, Christopher Mintz-Plasse
Genres: Comedy
Continuity mistake: When young Becca is looking at the drawing, her hands change position instantly. (00:17:20)
Trivia: Actor Christopher Mintz-Plasse was only 17 during the filming of the movie, creating some problems with shooting due to child labor laws. During pre-production, he was not allowed to see certain props or items from the film (such as Seth's phallic drawings), and his sex-scene had to be very carefully monitored and edited, as certain "actions" (such as too much skin, certain types of movements or positions, etc.) would violate the law.
