In Time star Justin Timberlake has come a long way since his crooning days with N'Sync. He has gone from being a curly-haired pop singer to a sexy solo act to a Saturday Night Live sensation and to a sophisticated actor and action film star -- all in the span of 11 years.

Is there anything he hasn't done?

I would love to do a musical one day, he told David Letterman. I think there might be a way to redefine what that is for this era.

He seems to be taking his acting success in stride.

Comedy, in general, is the most disarming, he told National Public Radio in an interview. It kind of breaks this wall down that I feel like people have because they have some perception of who you might be.

Here are photos of Timberlake throughout the years.
