The show's initial pilot, developed for the 2006–07 television season, was substantially different from its current form. The only characters from the initial pilot that were kept for the reshot pilot for the series were Leonard and Sheldon (portrayed by Johnny Galecki and Jim Parsons respectively and named after Sheldon Leonard). The cast was rounded off by two female leads: Canadian actress Amanda Walsh as Katie, "a street-hardened, tough-as-nails, woman with a vulnerable interior" who the boys meet after she breaks up with her boyfriend and invite to live in their apartment (Katie was replaced by Penny in the second pilot); and Iris Bahr as Gilda, a scientist colleague and friend of the boys who was threatened by Katie's presence. The initial pilot used Thomas Dolby's hit "She Blinded Me with Science" as theme music. Find out and discover what will happen next by watching The Big Bang Theory s06e06.
