In the new movie Osmosis Jones, the main character, Osmosis Jones is played by Chris Rock and the White Blood cell assistant Leah is played by Brandy. In the part where Osmosis Jones and Leah are both standing in the chief's office, Osmosis Jones accidentally says "Hey Brandy, I mean Leah." I don't know if too many people noticed, but see if you can catch it!
This is the only slip-up posted for this movie, just 3 different times... also, in Star Wars: A New Hope, when Luke gets out of his X-Wing after blowing up the Death Star, and Leia runs up to him, Luke yells "Carrie!". Carrie Fisher is the actress's name.
