Ben Stiller remembers Robin Williams as a 'genius' and 'a really genuine person'

NEW YORK, Dec. 14 (UPI) -- Ben Stiller says it was "a thrill" to have starred in three Night at the Museum movies with Robin Williams before the Oscar-winning actor died last summer.

"I always was excited to work with Robin because I've always been a fan of his since I was a kid -- since I was like 12 or 13 when Mork & Mindy came on -- so, I never got over that element working with him on any of the movies," Stiller said at a press conference Friday. "It was just always a thrill for me. He is -- he was amazing. He was a genius. But, for me, the thing that I take away from working with him, is that he was so kind and generous to everybody -- like every, single person that would come up to him in any way. It was pretty amazing to watch and he set a really high bar for that and he was a really genuine person."

Co-starring Steve Coogan, Ricky Gervais, Dan Stevens, Owen Wilson and Rebel Wilson, Night at the Museum: Secret of the Tomb is to open in U.S. theaters Friday.

Williams committed suicide last August after years of battling depression. He was 63.
