Actor Diane Keaton says she used to feel intimidated by Robert De Niro, but after working with him in The Big Wedding, she no more feels the same. Keaton stars alongside De Niro in the new movie, which releases in October, reported Contactmusic. “I did a movie with him called Marvin’s Room a long time ago, but he was a producer. I didn’t really know him and he was intimidating to me. But things change,” she said.
