Three screen goddesses - Betty Grable, Lauren Bacall, and Marilyn Monroe - star as golddigging models blessed with fabulous looks but limited brain power. The three blondes pool their resources and conspire to nab millionaire husbands, renting an expensive penthouse to lure in their likely prey. But with Rory Calhoun, Cameron Mitchell, David Wayne, Fred Clark, Alex D'Arcy, and William Powell playing the desired millionaires, the ladies are pushed to the end of their wits as they try to decide whom to wed....

'How To Marry A Millionaire' was the first movie to be filmed in CinemaScope, but 'The Robe' (1953, directed by Henry Koster) beat it to the cinemas.
