Which was Raj first movie?

It seems you're asking about Kunal Nayyar, who played Raj Koothrappali in the sitcom "The Big Bang Theory."

Kunal Nayyar's first movie was "The Namesake" (2006), which was a dramatic film directed by Mira Nair.

While "The Big Bang Theory" was his breakout role and the one he's most well-known for, "The Namesake" was his first major film appearance.
