I don't tend to make lists like these because the fact is, none of the actors in them are ever that bad.
So for example, while Robert Pattinson, Ryan Reynolds, Brendan Fraser and Adam Sandler have been in a lot of bad movies and delivered bad performances in them I don't think they're really that
bad, each one of them has delivered one decent performance at least. The work of an actor depends largely on the directors they're with and the scripts they're, which would explain why Sandler's performance in Punch Drunk Love, a PTA film, is a league above anything else he's done in terms of performance. The 10 worst actors of all time are probably ones we've only seen in some B movie from the 70s. The only exception I'd make to this is Taylor Lautner
, and when singers like Rihanna act in movies.
