Inspired by friend and co-star Katherine Heigl’s success on the big screen, Grey’s Anatomy star T.R. Knight is clamoring to leave ABC’s Emmy Award-winning medical drama in hopes of transitionng to a career in feature fillms.

The actor, who plays Dr. George O’Malley on Grey’s, has asked the network and show producers to be released from his contract; a request that is likely to be granted, according to several media outlets.

“He’s seen what his friend (Heigl) has done with her career — lots of people in the industry said she wouldn’t translate to film and she has. He wants more than what he can get from ‘Grey’s,’” one insider has revealed to MSNBC.

“He’s not inspired by his story, by George,” the source says. “He’s convinced he can do films. It’s as simple as that.”
