It seems amazing that Kaley Cuoco-Sweeting was once not a part of The Big Bang Theory. But when the show was pitched in 2006 to the powers that be, it was actress Amanda Walsh that played the guysâ female friend, who was then named Katie. A FOX News piece revealed the pilot with Walsh was not picked up, and it was later re-shot with Cuoco. A profile in Vegas magazine, published when the show was in its fifth season, revealed Cuoco actually tested twice for The Big Bang Theory. It was not until the first pilot failed that she was chosen for the series.
