5. Mike Myers
Austin Powers was a long time ago and Wayne's World even longer, though he has had the success of Shrek to fall back on, though even that franchise has now more than over-stayed its welcome. His fall from grace however is more down to his horrible choice of live action roles than constantly going back to the well for another outing as the green ogre. While the signs were beginning to show with Goldmember, even his most vocal of critics wouldn't have been able to foresee what would follow. First up was the title role in The Cat in the Hat, which made him look like a poor man's Jim Carrey, and as bad as that was, it's nothing compared to the shambles that it is The Love Guru. Myers' comedy has always been rather divisive, but The Love Guru was flat out unfunny. The only thing he achieved with these two films was to make people wonder when exactly Mike Myers lost his damn mind? How could the guy that created two of the most popular characters of the last twenty years or so get it so wrong? As of now, it seems that Myers' career as a leading man in comedy is over; another Austin Powers won't fix it and considering he co-wrote, produced and starred in The Love Guru, I doubt that anyone will allow him to create an original character again. If he really wants to do it then I would suggest that he dust off Dana Carvey and finally put out Wayne's World 3. He may be concerned about ruining the legacy, but how much worse could it possibly get? Party on Wayne!
