Brad Pitt and Angelina Jolie Unbutton ‘Benjamin’

Angelina Jolie, 33, and Brad Pitt, 45, led a crowd of celebrities at the West Coast premiere of The Curious Case of Benjamin Button at Mann’s Theatre in Westwood Monday night.

Angelina looked simple yet elegant with her hair slicked back and in a black, strapless Versace dress complimented by dangling gold earrings by Ralph Lauren.

Companion Brad sported a Tom Ford tux with an almost 70s-era size bowtie and the Oil Can Harry mustache he’s been wearing for his film with Quentin Tarantino (Inglorious Basterds).

The couple graciously signed autographs for fans. Jolie reportedly almost fell over the crowd-control railings at one point during the signing.

Celebs in attendance included Button co-stars Cate Blanchett, 39, (a recent Hollywood Walk of Fame star recipient) in an Alexander McQueen beige dress with a jewel-encrusted overlay. A flowy Tilda Swinton, 48, wafted in with a peach, beige and white striped Rodarte gown.

Jennifer Lopez pursed her lips in her usual “come, hither to the J. Lo” pose and looked slinky in white, as Eva Longoria went with royal-blue silk.

Also on the red carpet were Brad’s parents, Bill and Jane Pitt, who posed for pictures with their son and his companion.

Rumors abound that Jane Pitt has remained good friends with Brad’s ex-wife Jennifer Aniston (an admitted big fan of Brad’s new film), but it appears as if Mrs. Pitt has accepted her son’s new love, and the mother of his children.

The movie, based on an F. Scott Fitzgerald short story written in the 1920s about an 80-year-old man who ages backward and experiences romance (with Blanchett and Swinton) and loss, is already garnering Oscar buzz.

The LA Times raves about “an astonishing film that gets you thinking about love, time, aging, youth, impermanence, relationships, faith, communication and all the people who’ve had an impact—big or small—in your life.”

The special effects used to make Brad age backward in the film are also receiving astounded praise.

Pitt and 46-year-old director David Fincher appear to have a major hit on their hands, to go along with their previous successes together: 1995’s Se7en and Fight Club from 1999.
