3. John Travolta - Battlefield Earth (2000)
I'm sure that a few people thought that John Travolta was pretty nuts before they saw him as a weird-skinned alien freak in the Godawful sci-fi flick
Battlefield Earth, but before this movie went into theatres and people began to realise that John Travolta wasn't quite the guy they thought he was, the man was considered to be pretty cool. That's to say,
Pulp Fiction had brought him back into popular demand, and he'd just made
Face/Off. I mean, that's cool, right? In a '90s sense. But this movie marked a turning point, I think. A turning point in the minds of everyone who suddenly realised that John Travolta had no idea what he was doing, or why he was doing it.
Battlefield Earth, of course, is a movie based on a book by Scientology founder L. Ron Hubbard, which is all the information you really need to know to make up your mind about this. John, as "Terl," is truly terrible in the movie in every sense. At least we got dialogue cues as good as Crap-lousy ceiling! I thought I told to get some man-animals in here and fix it," though.
