Rising Broadway star Jonny Orsini, who debuted with Boston’s Company One a few years back, described to an awed female fan in New York the other night how he retrofitted his physique to play Nathan Lane’s inamorato in “The Nance.” “I had to stop going to the gym,” he said. His nude scene, emerging from a bathtub, doesn’t faze him, but as a straight man he did have to adjust going in for the kiss: “To feel stubble against my face — I’m not used to that,” he said. Luckily, Orsini finds Lane “just so lovable.” He can be seen next with Kristen Wiig in “Girl Most Likely,” which screens at this week’s Nantucket Film Festival. . . . Meanwhile, this weekend’s Provincetown Film Festival added a surprise screening: director Brian De Palma‘s “Passion,” starring Rachel McAdams and Noomi Rapace, had its US premiere.
