Singer/actor Justin Timberlake credits his role as Napster co-founder Sean Parker in The Social Network with furthering his acting career.

The SexyBack hitmaker landed several small film roles before appearing in the 2010 movie about founder Mark Zuckerberg, but he feels David Fincher's Oscar-winning drama properly launched him as an actor.

He tells U.S. breakfast show Today, "I'll tell you what sort of changed things for me was literally when (director) David Fincher hired me. It did open up a huge door for me. And the opportunities started to... happen."

One opportunity Timberlake could not pass up was the lead role in Joel and Ethan Coen's upcoming music movie Inside Llewyn Davis.

He continues, "Before we started working on that movie, I randomly ran into Matt Damon and he said something that stuck with me. He said, 'You know the Coen brothers, that's... a call that any actor, it doesn't matter what age, you just hope that one day you get a shot at that.' I was kind of blown away at that.

"If I would've got a call from Joel and Ethan Coen saying, 'Hey, we'd like you to write music and work on some music in our film,' I would've peed in my pants."
