Winona Ryder insisted she’s more than just a pretty face at the party for her new movie “The Iceman” Monday. The actress was heard telling a guest at the bash at Soho House that she received a 1600 on her SATs and could have gone to Harvard, but instead chose to shoot cult classic “Heathers.” Also celebrating at the Grey Goose bash was Michael Shannon, who told us his ’70s-style facial hair in the flick about a mob hitman isn’t real. “Sometimes it would come off,” he told us. “I’d just put more glue on and stick it back on my face.” The earlier screening at Chelsea Clearview was so packed that some guests were turned away at the door. James Franco spent so much time fooling around snapping pictures of Terry Richardson that the professional photographer was too late to get a good seat, being placed in the front row only to leave a few minutes into the movie. Justin Long spent the introduction of the film in the hallway before finding himself an empty seat.
