Until ironically both stars of The Iron Petticoat died within a month of each other in 2003, this film may have had until June 29 of that year of holding the record for having its two co-stars survive the longest. That was the day Katharine Hepburn died and Bob Hope died on July 27 and between them they had 196 years on earth. That's the only distinction The Iron Petticoat has.
Ben Hecht got on Bob Hope's case for allowing his gag writers to intrude in on his screenplay and story. Personally I can't believe they could have loused it up as bad as what his idea originally was. Katharine Hepburn is a female Russian jet ace who defects from the Soviet Union, not because of any disagreement with Communism, but because she was passed over for promotion in the Russian Air Force.
But the Americans still think they can convert her for propaganda purposes and who do they assign to the task? Not real life American air war hero James Stewart, but Bob Hope who plays the jet pilot who forced Kate's jet down. Who here really believes Bob Hope as a war hero pilot?
It's obvious Hope did interfere and it probably cost Hepburn some of her scenes, but the premise was so ridiculous I can understand why he thought the film needed help. As for Hepburn she throws on an accent that might be described as Maria Ouspenskaya on crystal meth.
Even such fine players as James Robertson Justice as the KGB man assigned to kidnap Hepburn back are wasted here.
The Iron Petticoat was a terrible idea made even worse in the execution. No wonder it's never shown in revivals of either Hope or Hepburn.
