Producers say the 42-year-old actor will serve as a presenter on the 83rd Academy Awards next month.
He'll join previously announced presenters Sandra Bullock, Jeff Bridges, Oprah Winfrey, Halle Berry and Marisa Tomei.
Bullock and Bridges won the top acting Oscars last year. Bridges is a nominee this year for his leading role in "True Grit."
Berry won the lead actress Oscar for 2001's "Monster's Ball." Tomei won the supporting actress prize for 1992's "My Cousin Vinny." Winfrey, who appeared on last year's Academy Awards, was nominated for a supporting-actress Oscar for 1985's "The Color Purple."
The 83rd Academy Awards will be presented Feb. 27 at the Kodak Theatre and broadcast live on ABC. James Franco and Anne Hathaway are hosting.
