#8 The Big Bang Theory Unaired Original Pilot
This post might come as a big surprise for many fans but let us tell you that Penny's character didn't exist in the original pilot. Instead, the show had another female lead named Katie who was a street-hardened, tough-as-nails woman with a vulnerable interior. Amanda Walsh played Katie's role in the unaired Big Bang Theory pilot. Upon being dumped by her boyfriend, Katie becomes homeless. Sheldon and Leonard meet her on a street. Leonard invites Katie to stay in their apartment for some days, not paying attention to Sheldon's objections! Katie was the original Penny, but the episode was not picked up by the CBS network. Kaley Cuoco replaced the Canadian actress Amanda Walsh in the aired pilot.
