Howard The Duck!

A sarcastic humanoid duck is pulled from his homeworld to Earth where he must stop an alien invader.

This is the film that caused George Lucas to sell off that which was LucasArts Graphical Department to Steve Jobs, which the latter turned into Pixar.

This is one of those films that is so horrendously awful you knew you didn't want to see it, until you do, then you wander around for a while, wondering where your brain cells went (from the moment you turned on this movie, they went "on vacation".)

This movie, while most of it is yes cornball, it does have it's moments. ("You can't barbeque him! He's my boyfriend!" and "Hey, Mr. Dark Overlord, those people stole your Card Key! (as in, lets make "Mongo" even more angry)) as well as many others.
