Continuity mistake: Charlie Brown is using a pen to write a book report. The black ink leaks and gets all over his hands. When he walks to his dresser to get a pencil, all the ink stains are gone.
Suggested correction: He wipes the ink on his shirt.
Continuity mistake: In "You're in the Super Bowl, Charlie Brown," Marcie's last name is Johnson. But, in "The Peanuts Movie," her last name is Carlin.
Suggested correction: The TV specials are not canon with the comic strip, the movie, or even with each other. Marcie has a different last name here because it is a different continuity.
Trivia: Charlie Brown inherited his name from creator Charles M Schulz, whose nickname was "Charlie." His last name "Brown" was taken from one of Schulz's co-workers at the Art Instruction Inc.
Suggested correction: The friend's full name was Charles Francis Brown, so Charlie Brown inherited his full name from the friend.
