Edward Norton saw his newest film, “The Bourne Legacy,” for the first time with the rest of the audience at its Ziegfeld Theatre premiere this week. Director Tony Gilroy admitted to us at the screening he was a bit nervous about what Norton would think. But Gilroy can rest easy. Norton, who plays a retired CIA agent and was accompanied by Shauna Robertson to the event, was overheard complimenting Gilroy at a Four Seasons dinner later. “Not a piece out of place,” he maintained.
