10. The End of The Affair: in The Nick of Time
The Couple: Ralph Fiennes and Julianne Moore
The Scene: There's nothing like a little extramarital nookie, you know? The way Sarah (Moore) and Maurice (Fiennes) run back to her house, clutching and clawing at each other, is the perfect example of clandestine passion that burns hot and fast and then dies down, inevitably. But, in this movie and many others, it's smoldering while it lasts.
What's So Sexy about It: These two are having sex under serious duress. Not only is it forbidden, but it's risky – and as the movie goes on, it gets riskier.
