The Iron Petticoat

The Iron Petticoat aka Not for Money is a 1956 British Cold War comedy film starring Bob Hope and Katharine Hepburn and directed by Ralph Thomas. The screenplay by Ben Hecht became the focus of a contentious history behind the production and led to the films eventual suppression by Hope. Hecht had been part of the screenwriting team on a similar themed Comrade X 1940.

Capt. Chuck Lockwood Bob Hope is eager to leave for London and visit his wealthy fiance Connie Noelle Middleton. A superior officer named Tarbell Alan Gifford cancels his furlough, ordering Chuck to sell the Soviet aviatrix on everything that is good about America and convince her to permanently come over to their side. The colonel even dangles a 100,000 bonus if Lockwood succeeds.Vinka is pursued by her former lover, Ivan Robert Helpmann, an engineer. She shows no interest in Chuck and is just as determined to sell him on Russian virtues as he is on influencing her. He describes her as cold and unappealing, but when Connie makes a surprise visit, Vinka strolls into Chucks room wearing little else but a pajama top and her military medals. Connie becomes increasingly angry, more so when she finds out that Chuck is not as welloff financially as he has pretended to be. ........
