As Moviefone happily pointed out on Friday, Justin Timberlake used to be a fairly successful musician. Who knew, right?! With all his acting performances over the last few years (both good and bad; hey, 'Love Guru'!), it's sometimes easy to forget that JT is an accomplished singer, responsible for some of the best Top-40 singles in the last decade. ("Cry Me a River": still awesome.) Which is what makes Timberlake's potential involvement in the Coen brothers's 'Inside Llewyn Davis' so intriguing: the film is about the '60s folk scene in New York's Greenwich Village, and Timberlake could find himself playing a folk musician if he accepts the Oscar-winning brothers's offer. Translation: worlds colliding!
