The Australian Academy announced the winners of the 6th AACTA International Awards Friday, honoring the best achievements in film excellence from the past year, regardless of geography.

The International Awards were a star-studded affair, with guests and nominees including Mel Gibson, Nicole Kidman (wearing Rochas), Dev Patel, Luke Hemsworth, Kenneth Lonergan, Harvey Weinstein, Sacha Baron Cohen and Emma Stone (wearing Gucci).

Ocean Park Standoff (featuring Samantha Ronson, Ethan Thompson and Pete Nappi) opened the Ceremony, which was broadcast in Australia exclusively on Foxtel Saturday. Among those taking the stage at The Avalon Hollywood were host Daniel MacPherson, and presenters Isla Fisher (wearing Monique Lhuillier), Julian McMahon, Alan Dale, Radha Mitchell, Damon Herriman, Luke Bracey and Simon Baker.

The musical "La La Land" added two more awards to its long list of accolades, receiving honors for Best Film and Best Lead Actress for Emma Stone, who is nominated for her role in the film at Sunday night’s Golden Globe Awards and the SAG Awards later this month.

Mel Gibson stepped up his Oscars campaign, receiving the award for Best Direction for "Hacksaw Ridge." The win follows an incredible run at AACTA’s domestic Awards in Sydney last month, where the film received nine awards, including Best Direction.

"Manchester By The Sea" received two AACTA International awards with director and writer Kenneth Lonergan receiving the award for Best Screenplay and Casey Affleck receiving the award for Best Lead Actor.

The remaining two performance awards went to Australian film "Lion." Dev Patel received the award for Best Supporting Actor while Australian actress Nicole Kidman received the award for Best Supporting Actress.

“From historical biopics and dramas to a tribute to the Golden Age of musical films, it’s wonderful to see such a dynamic mix of international and Australian achievement honored tonight and we’re delighted to see Australian’s Nicole Kidman and Mel Gibson honored for Australian films 'Lion' and 'Hacksaw Ridge,' " said AFI/AACTA CEO Damian Trewhella. “For the past six years, the voting patterns of the Australian Academy’s international chapter have often indicated those of the SAG Awards, Golden Globes, BAFTAs and the Oscars. I’d like to congratulate all winners and wish them every success throughout the awards season.”
