Noel Coward's Private Lives (2013)

Elyot Chase (Toby Stephens) and Amanda Prynne (Anna Chancellor) are glamorous, rich and reckless divorcees. Five years later, whilst on their second honeymoons with their brand new spouses, their passionate love for one another is unexpectedly rekindled, when they take adjoining suites at a French hotel. They both fling themselves headlong once more, into a new and exciting whirlwind of lust/love, without any thought for their partners present or their past issues.
