The photo is striking for so many reasons, but perhaps most of all for the stars’ casual and relaxed demeanor. Carrie Fisher sits between Mark Hamill and Harrison Ford, knees folded up against a table, holding a lit cigarette near an ashtray. Behind them, a wall lined with vending machines. Hamill — wearing a T-shirt from a movie he was in called “Fire Sale,” released at the same time as Star Wars — leans in, talking to an interviewer off-camera.
