Whether or not you give a damn about the theoretical physicist who helped develop the first nuclear weaponry, Oppenheimer is kind of a must-see—people are going to be yapping about this flick all summer long. You don't want to miss out on the Twitter discourse, do you?! Christopher Nolan's latest stars Cillian Murphy as J. Robert Oppenheimer and Emily Blunt as his wife, Communist biologist and botanist Katherine “Kitty” Oppenheimer. (More info on Kitty, please!!) The film also features Florence Pugh, A24 darling Benny Safdie, and a bunch of other actors that'll make you whisper "Wait, they're in this?!" to your friend in the theater.
