Stupid Movie Plot Holes: The Rock (1996)

"The Rock" is a classic action thriller from 1996 starring Sean Connery, Nicolas Cage, and Ed Harris. I'm going to go ahead and assume you've seen the movie because who hasn't! The problem is it's a great movie up until the climax where things stop making sense immediately. Ed Harris tells Connery and Cage that the last missile is in the "lower lighthouse". Nicolas Cage takes the green death balls out of the last rocket when The Candyman shows up and tries to stop him. Cage then ends up shooting the LAST rocket into Candyman's chest. Then for some reason he acts like that's not the last rocket.

He takes the juicy lime death pearls around WITH the guidance chip looking to stash them and takes one ball with him in his shirt pocket presumably just for fun. The last rocket is GONE. There is no way for the VX gas to be shot into San Francisco. The threat at that point is neutralized. Instead he wanders around for a final fight with that Willem Dafoe looking motherfucker. He could have just flared it up at the lighthouse and waited for backup to handle the situation and avoided the air strike on Alcatraz that nearly killed him, but then he wouldn't have been able to put the Grinch testicle in Willem Dafoe's mouth and punch it open which was basically the only reason this movie was made, right?
