The most groan-worthy aspect of the very first episode of The Big Bang Theory was the immediate (and inevitably unrequited) crush of sweet, nerdy physicist Leonard (Johnny Galecki) on new neighbor Penny (Cuoco), a waitress / aspiring actress / air-headed blonde. But series creators Chuck Lorre and Bill Prady were smart enough to play against stereotype by allowing the relationship to quickly implode once they dated and Penny's insecurities started to be revealed. The second season has been a series of triumphs for the young actress, as Penny became obsessed with online gaming, reached detente with Sheldon (Jim Parsons), and proved to herself that she has more resilience and depth than she realized. I'd love to see how she translates to the big screen.

I like Kaley, although I've only watched "Theory" once. I can definitely see her in movies!

I think the lovely Miss Cuoco has a shot at movie stardom. WHile I doubt we'll see her going toe to toe with Streep during Oscar season, she's a beautiful girl with great comic timing (which is rare) and as the above link mentions, has been able to make Penny more than just "the hot girl."

Give her a shot Hollywood! I'd much rather watch her than Kate Hudson sleepwalk through another stupid romantic comedy.

;)

I think she'd do alright in movies.

Kaley has already proven she can do both drama (Charmed) and comedy
(Big Bang Theory). I believe she will have a long career, possibly on both the small and big screen. You go, girl!
