There should definitely be a sequel but they woul obviously need new actors cos the others are too old. The chinese dude is actualy a stunt co-ordinator now.
There should be NO sequel....the original is a masterpiece, a real jewel from our childhood....we shouldn't ruin it with a sequel...
Anyways, the movie didn't leave space for a sequel, and the original actors were part of what made the movie great. A sequel with them NOW, older, would be too forced. And Mouth, as a character, should go untouched, as well as Mikey.
