Nicole Rocklin’s mom tried to be patient as she waited for her daughter to arrive at trendy Palihouse in West Hollywood on Sunday night. “I just want to give her a hug,” she said, of her producer daughter, who with producer Blye Faust, started the film project that would eventually become “Spotlight.” In 2009, Rocklin and Faust began optioning the life rights of the Globe journalists who uncovered sexual abuse in the Roman Catholic Church. Seven years later, the film won the best picture prize at the Oscars Sunday night. Rocklin was one of the VIPs who got hugs — and big cheers — when she entered the “Spotlight” after-party, which was packed by 11 p.m. Party guests were the loudest when director and co-writer Tom McCarthy arrived at the bar. McCarthy immediately thanked production company Anonymous Content, which joined with Rocklin and Faust to get the movie made, and Open Road Films, which handled distribution. Party guests included “Spotlight” stars such as Michael Keaton and Brian d’Arcy James, who play Globe reporters Walter Robinson and Matt Carroll. Also making rounds was Michael Cyril Creighton, who plays sexual assault survivor Joe Crowley in the film. Creighton was spotted chatting with real-life Globe reporter Sacha Pfeiffer, who’s played in the movie by Rachel McAdams.
