Mister Cory represented the first of several successful collaborations between star Tony Curtis and director Blake Edwards. Adapted from a story by Leo Rosten, the story details the rise of Mr. Cory (Curtis) from summer-resort busboy to high-stakes gambler. Along the way, Cory uses several close associates to get ahead, including sluttish socialite Abby Vollard (Martha Hyer) and Abby's virtuous young sister Jen (Kathryn Grant). Charles Bickford delivers a sturdy performance as the worldly-wise older gambler who becomes Cory's partner and severest critic. Judging by the number of times it has recently popped up on Cable TV, Mister Cory is one of the most enduringly popular of Tony Curtis' 1950s vehicles.
