PEOPLE's SAG Awards Gala: See photos from inside the party

There was plenty to celebrate Sunday night as actors gathered to honor one another at the Screen Actors Guild Awards — and then fête some more at PEOPLE's SAG Gala co-hosted by the Entertainment Industry Foundation. Among the big winners of the night with ample to toast about were the casts of Three Billboards Outside Ebbing, Missouri, Veep, and This Is Us (as evidenced by the big smiles on Chrissy Metz and Sterling K. Brown's faces here). Click on for a glimpse at all the party festivities.
