When Florence Pugh couldn't make it to the film's premiere due to other filming commitments, Andrew Garfield brought a life-sized cutout of her to fill her absence.
During the filming of a sex scene, Florence Pugh and Andrew Garfield let the scene go on for some time, as they felt comfortable with one another and had not heard "cut" yet. Once they realized they had been in the scene for way longer than they had anticipated, they looked up to see that the DP and boom operator had long since turned off their equipment and were facing away from the actors to give them privacy. In an interview with Josh Horowitz, Garfield said the humor of that moment "took the curse right off" of any remaining intimate scenes.
Director John Crowley also directed Andrew Garfield in Garfield's first feature film, Rapaz A (2007).
