His lack of on-screen roles after the OT was likely due to the car crash that busted up his pretty mug.

Which happened between Star Wars and Empire. Harrison Ford has a scar, and that hasn't hurt his career. Luke Skywalker casts a larger shadow than Han Solo in the minds of casting people perhaps?

It is obvious when it happened, as Mark's face never looked quite the same after Star Wars. A scar on your chin isn't quite the same as major reconstructive surgery. Frankly, I don't think Mark would have ever gotten the role had his face looked like that to begin with. But I agree that Luke Skywalker casts a larger shadow as you said.

Is it a popular theory that Luke was attacked by the wampa early in Empire to help "explain" this difference in his appearance?
