The Drop-Out Kid: Alec Baldwin Leaves 'Rock of Ages'

He's done it again! Just a couple of months ago, Alec Baldwin announced that he had dropped out of the troubled "Men in Black III." Now, THR is reporting that Baldwin has dropped out of "Rock of Ages" as well.

This move is a bit more surprising from Baldwin, as "Rock of Ages" is turning out to be a very highly anticipated movie. The flick is an adaptation of the jukebox musical, which features a collection of classic rock songs from the 1980's.

The show was a big hit on Broadway and during its national tour, so the movie should see a great deal of success as well.

Not only does the show bring a certain amount of appeal with it, but the cast continues to improve with each announcement. As it stands, the major names attached include Tom Cruise, Russell Brand, Malin Akerman, Catherine Zeta-Jones, Bryan Cranston, Paul Giamatti, and others.

It's quite a lineup, and would have only been improved by the ultra-talented Alec Baldwin, who continues to win award upon award for his work in NBC's "30 Rock." Baldwin's reason for leaving is unclear, although it's possible that he was never really fully on board in the first place: his involvement was announced on Twitter by director Adam Shankman.

Baldwin has mentioned in the past that he might be done with acting after his contract with "30 Rock" expires after next season. Could this be an indicator that Baldwin is going to make good on his retirement plans?
