The 10 most underrated 'Saturday Night Live' cast members of all time
You won't find Tina Fey, Eddie Murphy, Bill Murray or Adam Sandler on this list
4. Phil Hartman
Best known for: Unfrozen Caveman Lawyer; Frankenstein; Bill Clinton; Charlton Heston
Why: Of all the names on this list, Hartman is the one that seems most inappropriate to be here at first glance. During the years he was on the show, Hartman may have been the single most dependable performer they had. He could do almost anything, play almost anyone, and he also filled a spot in the show that was crucial: the older professional white dude. No one flipped out and started developing vehicles specifically as "Phil Hartman, Movie Star," and that's why he's on this list. He should have been one of the biggest names in "SNL"s history, and instead, he stayed a great team player, willing to play any part. He turned celebrity impressions into grand displays of razor-sharp ridicule, and he did it with perhaps the greatest radio voice of all time. Small wonder "The Simpsons" also made such good use of him over the years.
