You may be thinking of the movie Pitch Black with Vin Diesel.
GhouliesII
Little Monsters, Mr. Bean, Monsters VS Aleins
The "monsters" are bad due to the fact they are trying to kill you in the game.
It has not yet been confirmed if the same cast will be used for the Sea of Monsters, as little is known about the production of the movie.
It was Aaahh Real Monsters
It is called: "Monster Rolling 'Round" --------- The movie you are thinking of could also be 'Critters'.
I have heard that if they make the Sea of Monsters movie, it will come out in 2012. Because they still need to pick some of the other characters for the movie.
I don't think she has, mainly because she wasn't in the Sea of Monsters book.
I believe the one you are talking about is "Spirited Away" by Hayao Miyazaki
There isnt supost to be a Sea of Monsters movie, because the director messed up the Lightning Thief. So unless he can compleatly change the movie. There isnt gonna be one
Most movie monsters are neither, but instead are Bob.
There are rumors, but no confirmations or weither on not The Sea of Monsters will be a movie.
