Screwball sparks fly when Cary Grant and Katharine Hepburn let loose in one of the fastest and funniest films ever made—a high-wire act of invention that took American screen comedy to new heights of absurdity. Hoping to procure a million-dollar endowment from a wealthy society matron for his museum, a hapless paleontologist (Grant) finds himself entangled with a dizzy heiress (Hepburn) as the manic misadventures pile up—a missing dinosaur bone, a leopard on the loose, and plenty of gender-bending mayhem among them. Bringing Up Baby’s sophisticated dialogue, spontaneous performances, and giddy innuendo come together in a whirlwind of comic chaos captured with lightning-in-a-bottle brio by director Howard Hawks.
