I’m Not An A-List Actor, But I Play One On TV

In real life they are: Comedic actors Tracy Morgan and Jane Krakowski
On-screen they are: Insane 30 Rock co-stars Tracy Jordan and Jenna Maroney, stars of comedy show TGS With Tracy Jordan
Characters' biggest claims to fame: For Jenna that would be the musical version of Mystic Pizza. For Tracy, he's best known for being a spokeman for the Funcooker and for singing the song "Werewolf Bar Mitzvah". Spooky scary!
Why they aren't as famous as their on-screen personas: Both actors had supporting roles on comedy shows (Krakowski was on Ally McBeal and Morgan was on SNL) but they have never successfully crossed over into film, and 30 Rock, much as we love it, is not America's Favorite Sitcom
Real life star ratings: B-minus-list
Star Potential: We're thinking these guys might just stay with their character-driven roles that will keep them from breaking out too much. B-list.
