Brad Pitt fans will have three more years to watch the actor in new films, as the 47-year-old recently announced that he will be quitting the job when he turns 50.

Three years, he told Australia's 60 Minutes when asked how much longer he'd like to be in the business for.

And then what?

Hell if I know. Hell if I know. I am really enjoying the producing side and development of stories and putting those pieces together. And getting stories to the plate that might have had a tougher time otherwise, so . . . you know, I have gotten away with a few things in writing and I have been pissed off about a few things, Pitt said.

Born William Bradley Pitt on Dec. 18, 1963, the Oklahoma native struggled with a few uncredited film roles in the late '80s before landing short gigs on the TV shows Growing Pains and Dallas.

Then came the films Happy Together, Cutting Class, Thelma & Louise, Johnny Suede and Cool World.

In 1992, Robert Redford hired Pitt to play Paul Maclean in the period piece A River Runs Through It, earning Pitt much praise for his work.

From Interview with the Vampire to Seven Years in Tibet, to Fight Club and Ocean's Eleven, Pitt has continued to diversify his roles on the big screen. In 1995, he won a Golden Globe award for his role as mental patient Jeffrey Goines in Terry Gilliam's 12 Monkeys.

Over the years, Pitt's personal relationships have received as much attention as his films. Before the birth of Brangelina, Pitt dated Juliette Lewis, Gwyneth Paltrow and was married to Jennifer Aniston for five years.

Now, Pitt and longtime partner Angelina Jolie are parents to six children - Maddox, Pax, Zahara, Shiloh, Knox and Vivienne.

Thanks to his films The Tree of Life and Moneyball, Pitt has been receiving Oscar buzz this year for his roles as Mr. O'Brien and Billy Beane, respectively. On Nov. 18, Pitt's voice will appear in Happy Feet Two, the highly-anticipated sequel to the 2006 animated film.

2012 is lined up with the crime drama Cogan's Trade, based on the 1974 novel by George V. Higgins, and the post-apocalyptic horror film World War Z, based on the Max Brooks novel.

Pitt turns 48 years old on Dec. 18.
