Allen won the award for Best Original Screenplay for the romantic fantasy at the Writers Guild Awards in Hollywood Sunday night. The film stars Owen Wilson as a modern Hollywood writer who gets a chance to hang with his literary idols in the 1920s Paris of Hemingway and Fitzgerald.
With his biggest hit in decades, it's the fifth time Allen has won the award.
"The Descendants" won the award for Best Adapted Screenplay. Director Alexander Payne shared the honor with co-writers Nat Faxon and Jim Rash. Based on the novel by Kaui Hart Hemmings, the film stars George Clooney as a Hawaiian dad struggling to tend to his two daughters after a boating accident puts his wife in a coma.
Breaking Bad, Homeland and ABC's Modern Family were the big winners in the television categories.
Both movies also are in the running for best picture at next Sunday's Academy Awards.
The awards ceremony will air live on Sunday, Feb. 26, 2012 on ABC7.
