Imagine The Big Bang Theory without the character of Penny.
It nearly happened.
Originally, show creators came up with the character of Katie as the resident “hot girl." Unlike the miles of charm Penny presents, Katie came with an attitude as big as a Colorado mountain range and a frankness that was nothing short of intimidating.
Instead being of the neighbor across the hall, she was discovered on the street by characters Leonard and Sheldon after she was kicked out of her boyfriend’s living quarters following their breakup and stayed with Leonard and Sheldon in their apartment.
According to [The Big Bang Theory](series:200751) Wiki page, the writer’s envisioned Katie as a "a street-hardened, tough-as-nails woman with a vulnerable interior.”
They nailed it.
She was quite sexual though in a darker nature, having admitted to hooking up with the man who would eventually become her stepfather.
The pilot’s studio audience, surveyed after the taping, strongly disliked the character. CBS would pass on the pilot. In the subsequent second pilot, Katie became Penny and TV comedy history was changed for the better.
Canadian-born actress Amanda Walsh played the short-lived part. She has since going on to appear in a number of films and TV shows. She is famous in her home country for being one of the youngest ever video jockeys and has performed both standup and improv comedy.
Recently, she has appeared in the Canadian supernatural drama, Lost Girl, as Elizabeth Helm/Zee.
Still, one wonders, if in her private moments she wonders how close she really came to making “Big Bang Theory money”…
