Big bang is right! Big Bang Theory's Jim Parsons, Johnny Galecki and Kaley Cuoco are banding together to seek huge raises in new contracts for CBS' smash sitcom, multiple outlets are reporting. TV Guide reports that each lead earns $325,000 per episode, and could seek an increase to $1 million per episode. (The Hollywood Reporter confirmed that the stars decided to renegotiate their contracts together, as they did back in 2010.)

The number-one ranked series already locked in new contracts for supporting actors Mayim Bialik and Melissa Rauch, who have been promoted from recurring to regular characters, and will reportedly now make about $60,000 per episode -- with gradual increases taking them to $100,000 per episode by the end of their contracts. Stars Simon Helberg and Kunal Nayyar are also said to be looking for increases.

Warner Bros. Television did not comment.
