Y'know it's Oscars weekend when even the likes of Nicolas Cage are out on the scene ... in this case to honor "Killers of the Flower Moon" director Martin Scorsese and the cast of his Best Picture-nominated film.
TMZ got video inside the Bev Hills celebration, where Nic, himself an Oscar winner, and his wife Riko Shibata mingled at the Giorgio Armani-hosted party.
It's a rare sighting of Cage at showbiz events. He's more of a karaoke bar kinda guy, but, like we said, it's that kinda weekend in Hollywood.
Several other nominees were front and center ... including 'Flower Moon' star Lily Gladstone, who's up for Best Actress. She's already made history as the first Native American woman nominated for the award, and most critics say she's got a good shot to win Sunday night.
Her costar, and Best Supporting Actor nominee, Robert De Niro was there and looked to be in good spirits ... as he stopped to take a few snaps with folks. We also got shots of last year's Best Supporting Actor winner Ke Huy Quan, Olivia Munn and John Mulaney, Jane Seymour and Paris Jackson doing the small talk thing.
Other faces in the crowd -- Best Actor nominee Jeffrey Wright, Alessandra Ambrosio, Scott Eastwood and Callum Turner, who was not with his relatively new GF Dua Lipa ... unfortunate, for him, and everyone else there.
This was far from the only pre-Oscar bash in town this weekend -- the one CAA threw was just as star-studded, with a lot of the same names ... but just a different location, really.
