What made Marisa Tomei want to do “Before the Devil Knows You’re Dead?” “Sidney, Sidney, Sidney,” the thesp declared at the Cinema Society/Sagatiba’s post-screening party last week in Gotham.

Tomei, along with co-stars Philip Seymour Hoffman and Ethan Hawke, and of course director Sidney Lumet mixed with well-wishing celebs like Patricia Clarkson, Sheryl Crow and Lauren Bacall atop the Gramercy Park Hotel.

Hoffman said that the script’s clever structure and large themes attracted him to the project. “The tragedy that’s being explored is kind of bigger than the small story you’re seeing on the screen,” he explained.

Rome falls to Sharon Stone

ROME — “Romans, countrymen, lend me your wallets, for chrissake!” cajoled Sharon Stone during the Cinema Against AIDS auction and dinner at the Rome Film Festival on Friday.

Stone even hawked her own necklace at the request of a guest and helped raise $1.35 million as the film and fashion worlds hobnobbed with Eternal City notables at the candlelit affair in the central Spazio Etoile, followed by an after-party in the posh palazzo Fendi. Spotted sipping vino and savoring risotto at the Etoile tables were Mira Sorvino, Julie Taymor, Zoe Cassavetes and Sofia Coppola. “I’m gonna come over there and slap you,” Stone warned one guest who had refused to raise his bid.

Meanwhile, several guests had taken cover and were smoking in the crowded bathroom.
