Jim Carrey. That guy just  cracks me up. He is wacky and zany just funny as a guy can get.

  Seth Rogen has won me over in many of his films. I love how even when he makes a simple observation on people's behavior the way he does it, is hysterical.  Paul Rudd is another new favorite of mine I love him in "I Love You Man" I annoy the crud out of everyone walking around saying "slapping da bass. SLAPPING DA BASS MUN" His awkward humor reminds me a lot of myself when I try to make new friends lol. 
   A classic would be Jim Carry and his kind of crack head like comedy. I loved him ever since he was on Living Color. Steve Carell is another good. From annoying jerk to quirky weird guy trying to gain a social life he's always put a smile on my face. I can't wait to see the both of them in Burt Wonderstone.
   Ellen Page is one of my favorite female actresses. I adore her dry yet odd ball humor. Another person I can relate to a lot. I also really like Tina Fey. Though not a big fan of her usual female co-actor Amy Poehler. But I'm starting to think that may be when they are together Tina always plays the smart witty woman, while Amy seems to always be stuck as the middle age woman pretending to be 18. I seen a few episodes of Parks and Recreations and Amy is at her funniest in that.

Its between Adam Sandler and Jim Carrey for me.
But I think I lean more towards Adam Sandler :
His humor impacts me more

David Leary I guess.

I'd say Jim Carrey, Will Ferrel, and Steve Carrel. All funny actors that give me quite the chuckle when there is a serious moment and they go and just make it a fun moment.

In my opinion, Adam Sandler is the funniest actor out there.

I'll regret admitting this but Adam Sandler, Jim Carrey and Eddie Murphy.

I'd say Rowan Atkinson because his acting in Johnny English 1 makes me laugh

I don't watch a lot of movies, but I love Samuel L. Jackson as an actor for some odd reason. He can be pretty funny.

Pulp Fiction: "ENGLISH, MOTHERF*****, DO YOU SPEAK IT?" 

The Incredibles: "HONEY!!! WHERE IS MAH SUPER SUIT?!?!?!?"

Snakes on a Plane: "Enough is ENOUGH! I've HAD it with these MOTHERF****** snakes, on this MOTHERF****** PLANE! Everybody STRAP IN...we're about to open some f****** windows."

I think the funniest actor is Dave chappelle he is the funniest black comedian between Chris rock and the wayan brother and they are funny to but its hands down for me on Dave chappelle he is freaking hilarious.

Funniest actor was adam sandler in the 90s, he is terrible now but he was probably the best along with jim carey in that decade

Man; I have to choose ONE funny actor! That's a little too difficult!  I just finished watching a George Lopez movie. I found him quite funny. Most of his movies are pretty funny, but that's just me. 

Robin Williams is by far the funniest movie actor you can come by. He has handled every form of comedy and he's just great at it. My favorite movie of his is either Mrs Doubtfire or RV. Such a joyful thing to watch one of his movies.

alexanyways : Thank you for saying that, it made me watch some of his stand up comedy again, he's a genius.

I like John Cleese and Rowand Atkinson a lot. Jim Carrey is up there aswell.

Its a toss up between Bill Murray and Tim Allen. They both have done amazing jobs at humorous characters; Bill Murray as Dr. Peter Venkman in "Ghostbusters I and II" and Tim Allen as Scott Calvin in "The Santa Claus."

Adam Sandler is one of the funniest actors to me. Even though my favorite movie with him is Eight Crazy Nights which is cartoon form
