Gender-swapping an old movie joke about a screen starlet's director coping with her thick accent, this new trailer for the forthcoming Joel and Ethan Coen comedy Hail, Caesar! plays almost like a short film in its own right, complete with set-up, gag and punchline. That's actor Alden Ehrenreich (Beautiful Creatures) trying to get his line right for his director, Ralph Fiennes; the Coens' regular cinematographer, Roger Deakins, is behind the camera for this one.
