We’ve done the alternate ending to Big to death in a thread (yet it will likely rise from the dead like zombie again some day).
What are some other alternate endings people believe we’re shot, or just speculate on what possible it even less possible endings people might remember?
In the Big thread I think I mentioned the alternate ending to Groundhog Day where the groundhog runs away to a golf course and Bill Murray tries to blow him up. There is also the persistent myth that the Japanese version of King Kong vs. Godzilla has Godzilla winning the fight.
Of course you can toss in actual alternate endings to movies if you want to.
