There's a movie out: Jim and Andy: The Great Beyond, which is a documentary covering Carrey when he was filming "Man on the Moon". Apparently he channeled Kaufman so accurately that it went beyond method acting.
Agree that Kaufman was more of a performance artist than comedian - things like his wrestling antics (which wasn't really revealed as a joke until after he was dead) were so over-the-top that some people still don't know it was all a set up. Apparently Kaufman is pretty well-respected in the pro wrestling world because he played "the heel" so convincingly and without ever breaking character. Even his Kaufman's own brother went through a period where he wondered whether Andy's death was all a long hoax and that he would re-appear at some point.
