Big Bang Theory fans know Jim Parsons as Sheldon Cooper, a role he took on early in his career. Pictured here in 2004, Parsons made his on-screen debut in one episode of Ed in 2002. He went on to appear in TV movies and pop up as Tim in Garden State soon after.
Months before he joined The Big Bang Theory as Raj Koothrappali, Kunal Nayyar made his small-screen debut in one 2007 episode of NCIS, pictured here.
Melissa Rauch found her spot on The Big Bang Theory as Bernadette Rostenkowski. Pictured here in 2006, the actress earned her first on-screen credit the same year, appearing in the film Delirious.
