Steven Soderbergh apparently gave the star-studded cast of his new movie “Bitter Pill” one last fancy meal before heading to shoot on location in a prison. The director and Rooney Mara, Jude Law and Channing Tatum were spotted heading into A Voce Columbus on Wednesday night for dinner in a luxe private dining room at the Time Warner Center restaurant. But, sources say, they’re headed today to a federal prison in Otisville, NY to shoot. “It’s a real live prison, so it requires lots of special security,” a source added. We hear that distributor Open Road Films is looking to release the movie, about a woman coping with the imminent release of her husband from the slammer, in the first quarter of next year.
