This American actor is most famous for his 20-year stint playing Dr. Frasier Crane on Cheers and Frasier (he holds the record for the longest duration of portraying a character on TV, tied only with James Arness for Gunsmoke, not counting voice actors). One of the few, if not the only, actors to receive three different Emmy nominations for the same character on three different shows (Frasier, Cheers, Wings).
His second most famous role is that of Sideshow Bob (Krusty's former sideshow partner who tried to frame Krusty for armed robbery, but now plots to murder Bart after Bart proved that Krusty is innocent) on The Simpsons.
Played Beast in X-Men: The Last Stand. Also played Chuck Darling in the short-lived Back To You and starred in the ill-fated Down Periscope. Executive produced shows such as Girlfriends, The Game and Medium. He has had numerous problems with alcohol, having started drinking at age nine (but his family life has been so tragic it's hard to blame him). His daughter is Spencer Grammer. He also once flipped a Dodge Viper. Lest we forget that he was Gary the Rat, and appeared in both of Donbluth 's Anastasia adaptations.
A self-admitted "former Beach Bum from Florida". Known to be a Republican, and really smart (just take a look at his forehead).
