LOS ANGELES -- The multinational drama "Babel," girl-group musical "Dreamgirls" and quirky road trip comedy "Little Miss Sunshine" led the nominations for the 13th-annual Screen Actors Guild Awards, the organization announced Thursday.

All three films scored outstanding acting ensemble nominations In addition, "Babel" earned two supporting female actor nods for Adriana Barraza and Rinko Kikuchi. "Dreamgirls" scored supporting female and male actor nominations for Jennifer Hudson and Eddie Murphy, while "Little Miss Sunshine" produced female and male supporting actor nods for Abigail Breslin and Alan Arkin.

Also in the running for ensemble award are the casts of the Robert Kennedy-themed drama "Bobby" and crime-thriller "The Departed." Noticeably absent from the best ensemble nominations were awards season favorites Clint Eastwood's World War II epics "Flags of Our Fathers" and "Letters from Iwo Jima," and the Sept. 11 docudrama "United 93."

Surprisingly absent from both categories was perennial awards season nominee Jack Nicholson, whose earned high praise for his role as a ruthless mob boss in "The Departed." He's been promoted as a supporting actor during awards season but is arguably one of the lead actors in the film.

Instead, taking on DiCaprio for the lead actor SAG award are Ryan Gosling for "Half Nelson," Peter O'Toole for "Venus," Will Smith for "The Pursuit of Happyness" and Forest Whitaker for "The Last King of Scotland."

Up for the female actor SAG are Penelope Cruz for "Volver," Judi Dench for "Notes on a Scandal," Helen Mirren for "The Queen," Meryl Streep for "The Devil Wears Prada" and Kate Winslet for "Little Children."
