The Help and The Artist dominated the Critics' Choice Awards in Los Angeles on Thursday night, scooping the event's top prizes.

The film about the treatment of black maids in 1960s America landed three of the coveted acting honors, including a Best Actress prize for Viola Davis, while her co-star Octavia Spencer picked up the night's first award, Best Supporting Actress.

Davis told the crowd at the Hollywood Palladium, "I consider it an honor to pay homage to these woman who at that time period were not allowed to dream."

The ladies were handed another trophy, Best Acting Ensemble, but it was The Artist which was named Best Picture.

The silent movie also earned Michel Hazanavicius the Best Director honor and gained nods for Best Score and Best Costume Design.

George Clooney's chances of landing an Academy Awards nomination for his role in The Descendants were boosted when he was named Best Actor, while Christopher Plummer scooped the Best Supporting Actor for Beginners.

However, it was director Martin Scorsese who was the toast of the ceremony - as well as winning the Best Documentary Feature prize for George Harrison: Living in the Material World, he was also handed the Broadcast Film Critics Association's second Critics' Choice Music and Film Award.

Bob Dylan played in honor of Scorsese, who received his award from Leonardo DiCaprio and Harrison's widow Olivia.

The moviemaking icon told the audience, "Such a great honor and an amazing performance by the great one, Bob Dylan. This award has a very special significance to me."

Sean Penn was honored with the prestigious Joel Siegel Award for his humanitarian efforts in Haiti, and the prize was extra poignant for the actor as it landed on the second anniversary of the 2010 earthquake which devastated the nation.
