The Big Bang Theory stars Johnny Galecki (Roseanne, Hope & Faith) as Leonard and Jim Parsons (Judging Amy, Garden State) as Sheldon, two brilliant physicists with the kind of "beautiful minds" that understand how the universe works. But none of that genius helps them interact with people, especially women. All this begins to change when a free-spirited beauty named Penny (Kaley Cuoco - 8 Simple Rules for Dating My Teenage Daughter) moves in next door. Sheldon, Leonard's roommate, is quite content spending his nights playing Klingon Boggle with their socially dysfunctional friends, fellow Caltech scientists Wolowitz (Simon Helberg - Studio 60 on the Sunset Strip) and Koothrappali (Kunal Nayyar). However, Leonard sees in Penny a whole new universe of possibilities ... including love.

The Big Bang Theory was created and is executive produced by Chuck Lorre (Two and a Half Men) and Bill Prady (Gilmore Girls, Dharma & Greg). The series is from Chuck Lorre Productions, Inc. in association with Warner Bros. Television.
