Tina was one of SNL’s best writers. She did the heavy lifting for 30 Rock, or whatever that TV series was. She’s also made several movies. Not bad for a one hit wonder.
Mean Girls, which she wrote the screen play for and starred in, was better than just about any of the movies driven by SNL characters.
(The other adults in the movie were pretty much all SNL alumni, Tim Meadows, Ana Gasteyer, Amy Poehler.)
