HYSTERIA is a lighthearted romantic comedy based on the surprising truth of how Dr. Mortimer Granville came up with the world's first electromechanical vibrator. Academy Award® nominee Maggie Gyllenhaal (CRAZY HEART, NANNY MCPHEE RETURNS) and Hugh Dancy (ADAM, CONFESSIONS OF A SHOPAHOLIC) lead an accomplished cast in this untold tale of Victorian discovery, as a young doctor's quest to work out the key to women's happiness leads him to his own.
