Sextette (1977)

Marlo Manners (Mae West) is enjoying her honeymoon with Sir Michael Barrington (Timothy Dalton), husband number six. As luck would have it, an international conference is taking place in the same hotel and the Russian delegate (one of Marlo's former husbands) is threatening to derail the negotiations unless he can have one more fling with his ex. Adding to the complications is a tape Marlo has made detailing all of her affairs and scandals, which her manager is desperately trying (and failing) to destroy.
