Robin Williams' Widow, Susan Schneider, Attends His Movie Premiere

— -- The New York City premiere of one of Robin Williams' last films, "Night at the Museum: Secret of the Tomb," was held on Thursday night.

And the actor's widow, Susan Schneider, was on hand for the event.

People magazine reported that she attended the premiere looking "composed" and "at ease," and chatted with filmmakers and Williams' co-stars at the after party.

"It's very, very sad," co-star Ricky Gervais told the magazine of Williams' shocking death. "He was amazing performer – an icon before I met him, then a friend."

Williams was 63 when he died this past August of an apparent suicide, leaving behind his wife and three children from previous marriages.

"We're doing okay," his oldest son Zak told Us Weekly last month of his family. "We're acclimating to the new normal. Everything is step by step."
