I have a very clear memory of a movie I watched as a child. It may have been of a scientist tinkering with human nature, but my memory is that a man, having a severe itch on his shoulder, scratches and scratches and then one day he wakes up, looks in the bathroom mirror, and an eyeball has popped out on his shoulder. Eventually, an entire head grows out of his shoulder, and by the end of the movie the entity and the man literally split in half into two separate people.
I can't say that this traumatized more than it fascinated me, as I watched it at least a few times. Do you guys have any idea what movie this is? Thanks for any help.
UNK SEZ: I think I might have this one Karen! I'm guessing it's 1989's HOW TO GET AHEAD IN ADVERTISING!
