Wes Anderson's The Grand Budapest Hotel took home the top film prize at the Writers Guild of America Awards on Saturday (14Feb15).

The movie, based on the adventures of a guest house concierge, beat competition from Oscars favourite Boyhood and Foxcatcher to be awarded the accolade for Best Original Screenplay, for co-authors Anderson and Hugo Guinness.

Graham Moore picked up the Best Adapted Screenplay award for The Imitation Game, a film about World War Ii code-breaker Alan Turing, and he paid tribute to his subject at the ceremony in Los Angeles, saying, "He was probably the greatest genius of his generation and I am a screenwriter from Chicago. So it's very strange to be standing on stage now when he should be."

Brian Knappenberger took the award for Best Documentary Screenplay for The Internet's Own Boy: The Story of Aaron Swartz, and True Detective led the television categories, winning Best Drama and Best New Series, while Louie was named Best Comedy.
