Robin Williams’ widow, Susan Schneider, made her first public appearance since his August death at the premiere of one of his last films, Night at the Museum: Secret of the Tomb.

Schneider posed for photos on the red carpet wearing a simple black dress and later mingled with his colleagues at the American Museum of Natural History’s after party.

His co-stars remembered him at the event, with Ben Stiller telling People if he were there "I think he'd be making everyone laugh a lot more than I am."

“I will never forget his generosity,” he also told Variety. “I got to work with him a few times over the years, and he was the kindest person.”

Another co-star, Owen Wilson, said “There will never be anyone like him.”

Williams committed suicide in August. He was 63.

Shortly after his death, Schneider revealed he had been battling early stages of Parkinson’s disease.

Night at the Museum: Secret of the Tomb will hit theaters Dec. 19.
