I love Jim Carrey hes such a talented actor, Do you know who he is? 
I do!  I first saw him on the show "In Living Color" in 1990.
That was a great movie, I always wanted to visit him in person and get an autograph, Does Jim Carrey do autographs? 
I'm not certain if he does autographs or not.  The last movie that I remember him in was "A Christmas Carol" in 2009.
I think he has some of the best comedy films in my opinion, What are some of his best movies? 
I think some of the obvious ones are his best . . . . "Dumb and Dumber", "Liar Liar", and "The Mask."
I agree those are my faves, I have all of them on DVD, Isnt he getting old now? How old is Jim Carey? 
He was born on January 17, 1962, so he's 56 now.
Oh thats not too old, He looks pretty great for his age.
Yes, he probably stays in great shape due to his high energy slapstick performance style.
