Helen Mirren was in Prime Suspect. I think it is available on Netflix on DVD.
Thrillbilly is correct. The Cook, The Thief, His Wife and Her Lover is another revealing role for Ms. Mirren. That movie is a good complement to the recent thread about the German cannibal.
She is also in the current Calendar Girls.

That Peter Greenaway sure has produced some bizarre flicks.
