Jim Sturgess is a lucky dude, having worked with Natalie Portman and Scarlett Johansson in The Other Boleyn Girl and, now, with Kate Bosworth in the new nerd-gambling movie 21. Does it make him nervous to work amongst such, well, babes? "Yeah, certainly beforehand," he said at last night's 21 premiere. "And then you meet them, and they’re always just very normal, down to earth people. Before you meet them, you say, Oh my god, it’s going to be insane, and then, within an hour, they’re just the normal people that they are." Plus, the circumstances aren't always so sexy. First of all, Kate Bosworth had to get wasted for her sex scene with him: "We were both so drunk," she told People. "It was brilliant for about half and an hour," said Sturgess. "As we continued to drink…it just became sloppy and messy." And then there was the time he was introduced to Natalie Portman. “I met Natalie Portman in the middle of a field covered in cow shit,” the affable Brit told us. "We were stuck out in rural England; we were both learning how to ride a horse. It was the most unglamorous setting [in which] I could have met a celebrity like that," he said. We bet she still looked hot, though. —Bennett Marcus
