The Cook, the Thief, His Wife & Her Lover (1989) features a younger but just as talented Helen Mirren, not to mention the esteemed Michael Gambon and Tim Roth. It is a well-crafted film and certainly worth the watch if you have never seen it.
The wife of an oafish restaurant owner becomes bored with her husband and considers an affair with a regular patron.
Any movie with Helen Mirren is worth watching.
No argument here!
