Revealing mistake: At the hockey game in the beginning of the movie, when the players crash into the boards behind the goal, the logos on the players uniforms are backwards or opposite of what they really should be. The Devils logo appears this way several other times in the movie as well.
Little Black Book (2004)
1 revealing mistake
Directed by: Nick Hurran
Starring: Kathy Bates, Brittany Murphy, Holly Hunter, Ron Livingston
Other mistake: In the end when everyone is on the Kippie Kann show, they show the clip of Lulu and Joyce at the restaurant. It shows Lulu saying, "I'd say it's nice to see you, but then I'd be lying." In the restaurant scene, Lulu never says that.
