Check out every smile and selfie from inside the Barker Hangar at the Santa Monica Airport where the biggest names in movies and TV came together to celebrate the past year in film.

Just a few of the stars we caught grinning and taking pics ... Margot Robbie, Nicholas Braun, Charlotte Stoudt, Mimi Leder, Jennifer Aniston, America Ferrera, Ariana Greenblatt, Kristin Hahn, Tom Holland, Billie Eilish, Oprah, Charles Melton, Julianne Moore and Jesse Plemmons.

Steven Yeun gets his own shout-out here because he went beyond smiling straight to howling with laughter while Bill Hader smiled alongside him. Bill's lady love Ali Wong was at the event as well.

"Abbott Elementary" stars Quinta Brunson and Janelle James looked happy to be at the event too ... not surprising since they're each up for individual acting awards for the show, the second year in a row they've received nods. Good luck, ladies!

In any case, all of the stars seem to be happy to be inside ... probably excited to get off the chilly red carpet they walked after arriving -- hey, it might be L.A. but it's still winter!
