Funniest Female SNL Alumnae
There is nothing particularly entertaining about this list, but it got me to thinking about something: there has never been an SNL alumna who became a film star on the level of Chase, Belushi, Farrell, Murphy, Murray, Myers, Sandler and Farley. In terms of film success, I don't know if any alumna even belong in the second tier with the likes of Spade, Schneider and Ackroyd.
Tina Fey is a big star and a huge talent, but (1) she is not a film star and (2) she was basically the head writer on SNL, not a sketch performer. Her biggest on-camera job on the show was the Weekend Update. Her impressive gifts as a comic actress didn't emerge until 30 Rock, and it was that show rather than SNL which made her a bona fide TV superstar.
Julia Louis-Dreyfus is also a monster TV star. In terms of pure success, Tina and Julia (as well as Seth Myers) are up there with the others listed above, but they are TV stars, not film icons.
Can Kate McKinnon break through in films? I think she may be the most talented female performer in the history of the show. She will do anything for a laugh, and she can make you cry as well, so it's possible for her to go nova, but I'll be surprised if it actually happens. I think she's going to end up as more of a niche performer like Phil Hartman or Bill Hader.
