Plot hole: It is firmly established in the last half of the film that movie characters and movie weapons do inflict damage and death in the real world. However, early in the film, a bundle of dynamite comes straight through the movie screen and explodes in the real world movie theatre. That quantity of dynamite should have gutted the theatre, easily; but, when Danny Madigan and Jack Slater cross from the movie world back into the real world, there is absolutely no damage to the theatre.
