10 Secret TV Pilot Episodes You Didn't Know Existed

10. 30 Rock - From Sketch Show To Sitcom

30 Rock was conceived in the mind of Tina Fey while she was the head writer on Saturday Night Live. She believed her experience behind the scenes was unique enough to warrant its own tv show, and boy was she right!

However, originally 30 Rock was planned to be a lot closer to SNL than it came out being. In the first pilot, the show had more of an SNL vibe, with quick flashes of scenes and more of a focus on the sketches that happen on The Girlie Show (the tv show that Fey's character works on). Another leading factor into the SNL-esc feel was the hiring of legendary SNL alum Rachel Dratch as the star of The Girlie Show.

Once the pilot was complete, Tina Fey and the other producers decided to move 30 Rock further away from Fey's previous job. They did this by focusing more on Fey's character and what she gets up to behind the scenes. They also recast Dratch's character with a more traditional sitcom actress Jane Krakowski; instead of a character actress like Dratch.

SNL fans were gutted when the apparent original conception of the show was leaked, as they felt cheated by the left turn Fey made when tinkering with the pilot.
