The party took place at Ellison's restaurant Nikita, a pricey Mediterranean eatery that looks out over the ocean in Malibu, California. Here, Vanity Fair's Julie Miller and Haute Living's Laura Schreffler enjoy the patio with another guest.
Ellison hosted the party with girlfriend Nikita Kahn, an animal rights activist and philanthropist.
Kahn gave a rallying speech during the party. "Recently, we had a lot of very young seals come up on the beach in Malibu because they were too small and weak to feed themselves,” she said. "The California Wildlife Center came to the beach, picked them up, fed them, and cared for them until they were big enough and strong enough to be released back into the wild. I didn't even know an organization like that existed. I was so impressed with how they responded to the emergency, I decided I had to get involved."
The restaurant was beautifully set for the occasion.
Ellison seemed to really enjoy the company.
Oscar-winning director Kathryn Bigelow was among the celebrities who turned out to support the cause.
Ellison's daughter Megan has produced a number of films, including "Zero Dark Thirty," which Bigelow directed.
