As Hollywood actors pitch their tents on either side of the strike authorisation vote, the Screen Actors Guild announced its nominees today [December 18] for the 15th Annual Screen Actors Guild Awards on January 25.

Richard Jenkins, Frank Langella, Sean Penn, Brad Pitt and Mickey Rourke will contest the lead actor race while Anne Hathaway, Angelina Jolie, Melissa Leo, Meryl Streep and Kate Winslet are in the running for best actress.

Heath Ledger is nominated in the supporting actor category and Doubt, Frost/Nixon, Milk, Slumdog Millionaire and The Curious Case Of Benjamin Button are nominated in the best ensemble category.

Two randomly selected panels for television and film, each comprising 2,100 Guild members from across the US, chose this year's actor nominees.

Voting was completed by December 16 and the awards ballots will be mailed on December 26. The entire active membership of the Guild across the country will vote on all categories. Votes must be received by January 23.
