Yes (2004)

Synopsis
Filmmaker Sally Potter directed this artful meditation on the dynamics of the romantic and sexual relationship. She (Joan Allen) is an intelligent and gifted genetic scientist of Irish-American heritage who feels smothered in her marriage to a British politician (Sam Neill). While dining at a friend's house, She meets He (Simon Abkarian), a handsome Lebanese exile who was a respected surgeon in his homeland but now supports himself in London as a cook. He flirts with her, and She is pleased with his advances; weeks later, she contacts him, and an affair begins. However, despite their mutual attraction, He and She find it difficult to set aside their political and national differences for very long, as love and lust wage a quiet war against the conscience and the intellect. Yes also features supporting performances from Shirley Henderson and Sheila Hancock. ~ Mark Deming, All Movie Guide
