During the day, the A-listers both looked casual, with Emma in a simple ivory skirt and summery top and Bradley in a zippered jacket, untucked white shirt, and comfy pants.
For the red carpet, Bradley dressed up his look with a suede jacket, while Emma dazzled in a strapless, geometric, blue-gray fitted number.
During a recent Twitter chat for IMDb, director Crowe said working with Emma was "pure heaven." Kind of like her usual look on the red carpet!
