Those lists are stupid anyway because the people who are the top 50 worst actors of all time have never actually acted in anything that's going to be listed on IMDB. Instead they're the people that were so bad that they couldn't even get in a semi-known product.
In other news Rowan Atkinson is THE worst actor of all time.
As much as I dislike Cena, that Claire girl was like 100x worse than what Cena has ever been and thats saying something.
On topic: To say Rowan Atkinson is overrated is one thing but to pick him out out of every actor thats ever been on the TV screen or movie screen and single him out as the worst ever is indeed stupid. I wouldn't take those people too seriously.
