I really haven't checked the credits, but could Carol be the name of the woman that plays Kara, and he just messed up (Like that one munchkin in The Wizard Of Oz)?
But if you put on the subtitles you find out he actually says GIRL!! I checked it out. Do you really think that they would leave a huge mistake like that?? I think NOT!
I also thought that he messed up her name, but the captions do say "girl"...and if you listen to it again knowing this, it sounds right. Dennis Quaid just talks funny ^_^. Remember how he HAD an accent in the first 5 minutes of the movie, and then lost it? Perhaps it was his attempt at an accent again?
