Trivia about The Big Bang Theory

This was the second pilot produced for the show.

A different pilot was produced for the 200607 television season but never aired.

The structure of the original unaired pilot was different from the series' eventual form.

The only main characters retained in both pilots were Leonard (Johnny Galecki) and Sheldon (Jim Parsons), who are named after Sheldon Leonard, a longtime figure in episodic television as a producer, director, and actor.

A minor character, Althea (Vernee Watson), appeared in the first scene of both pilots that was retained generally as-is.

The show's pilot episode premiered on September 24, 2007.
