The eighth Rome Film Festival closed last night and unveiled its winners naming Scarlett Johansson Best Actress for Spike Jonze’s Her, in which Johansson voices a Siri-like Operating System but doesn’t appear onscreen, according to Deadline.

That’s a nice early accolade for Warner Bros., which releases the romance in limited release December 18 before expanding in January.

And it’s the first step in could be a groundbreaking awards season coup for Johansson’s voice-over performance in the pic, Deadline said.

Also nabbing top honors out of Rome were Kiyoshi Kurosawa, who won Best Director for Sebunsu kodo (Seventh Code), and Dallas Buyers Club, which landed Matthew McConaughey the Best Actor prize and also won the Audience Award. Scott Cooper’s Out of the Furnace was named best first or second feature.
