At the film's Los Angeles press day, Collider got the
opportunity to sit down with actor Sebastian Stan (who gives a terrific performance as Harding's mustachioed and impetuous ex-husband Jeff Gillooly) to
chat 1 - on - 1 about why he wanted to play this character, what he was most excited and most nervous about, the impression he got from meeting Jeff Gillooly, having Margot Robbie as a scene
partner, and what it means to be a part of the awards conversation with this film.
