Revealing mistake: Right at the end of the film when Sam, Patrick and Charlie are driving through the tunnel, when Charlie begins to stand up on the back of the truck, look slightly beneath his flapping jacket and you can see the safety wires attached to him.
The Perks of Being a Wallflower (2012)
1 revealing mistake
Directed by: Stephen Chbosky
Starring: Paul Rudd, Emma Watson, Logan Lerman, Ezra Miller
Factual error: In all of the cafeteria scenes, the food pyramid posters that can be seen on the walls are the updated 2011 versions, not the ones they would have had in 1991 and 1992.
Trivia: Emma Watson Sam said, "[Bob's] still trying to shag that waitress from the Olive Garden." Emma is an English actor, but the movie is a semi-autobiography of writer Steven Chbosky and is set in a suburb of Pittsburgh, 1991-92 school year. "Shag" is NOT (and was not) commonly used in the U.S. to refer to having sex. "Shag" in the U.S. is more commonly known as referring to a type of carpet, haircut, or dancing. (00:12:13)
