The Artist followed its Golden Globe win by taking top honours at the Producers Guild Awards as the silent film continues its run towards Oscar night.
Producer Thomas Langmann received the award handed out at the Beverly Hilton by the Producers Guild of America, as The Artist beat George Clooney's family drama and another Oscar favourite, The Descendants.
The Artist - starring Jean Dujardin - won best musical or comedy at the Golden Globes and The Descendants won best drama along with a best actor nod for Clooney, making the movies likely rivals for Best Picture at the Academy Awards.
The other nominees in the movie category were War Horse, The Help, Bridesmaids, Hugo, The Girl With The Dragon Tattoo, Midnight In Paris, Moneyball and another Clooney movie, The Ides Of March.
Along with honours from other Hollywood professional groups such as actors, directors and writers' guilds, the producer prizes have become part of the pre-season sorting out contenders for the Oscars, whose nominations come out on Tuesday.
HBO's saga of mobsters in Prohibition-era Atlantic City Boardwalk Empire won the producers' award for television drama series, keeping AMC's 1960s advertising agency drama Mad Men from winning its fourth PGA Award.
A team of seven producers, including Martin Scorsese, received the award for Boardwalk Empire, which also beat Showtime's Dexter, CBS's The Good Wife, and another HBO series, Game Of Thrones.
The ABC network's Modern Family took the award for best TV comedy series for the second year in a row, beating 30 Rock, The Big Bang Theory, Glee, and Parks And Recreation.
Other winners at the PGA awards included Downton Abbey for long-form television, The Adventures Of Tintin for animated film, Beats, Rhymes And Life for movie documentary, and The Colbert Report for talk and live entertainment shows.
