What ever happened to Billy Crystal? Did he retire?

Is Billy Crystal still in show business, or did he retire? As funny as he is, and as talented as he is, comedians such as he, Dana Carvey, and Jim Carrey seem to be keeping too much of a low profile these days. I can't even remember the last time I saw either of them in a movie. Dana Carvey is far far more talented than Adam Sandler in the fact that, just like Eddie Murphy, Dana Carvey can also imitate anyone and play multiple characters in a movie. Adam Sandler is'nt that funny, but yet he makes $35 million per movie. Eddie Murphy still only makes $20 million per movie. Does'nt Hollywood care about REAL talent anymore?
