Unless, of course, your name is William Atherton.
It turns out that it is possible to be too good of an actor. For years after the release of Ghostbusters, fans of the movie would see Atherton in bars and try to pick fights with him, presumably under the impression that he really does work for the EPA and really did try to hinder the efforts of a pack of wisecracking ghost hunters in 1984. Not even shaving his beard could prevent people from HOLY SHIT WE JUST REALIZED HE'S THE JERK FROM DIE HARD TOO.

Ahem. Anyway, the film's director, Ivan Reitman, mentioned on the DVD commentary that he ran into Atherton sometime after the film's release, and instead of greeting him as one might normally greet the man who made you internationally famous, Atherton was completely pissed off. Not only were people trying to fight him, but he also had random assholes shouting at him in public. In one incident that was absolutely horrible and totally not the greatest thing we've ever heard, a bus full of kids spotted him on the street and yelled "DICKLESS!" at him from the windows. The joke's on them, though; if any celebrity on Earth is likely to become a ghost and haunt the shit out of people who were assholes to them, it'd be this guy.
