Regarding Helen Mirren, you ought to check out 'Savage Messiah' (Ken Russell).  She is far more "exhibitionary" in that one than 'The Cook, the Thief, etc.'  She made my heart melt in 'Savage Messiah'...

Jenny Agutter ... ah, she was amazing.  She had a very revealing scene towards the end of 'Equus.'  She had one in 'Logan's Run' too.  She was just gorgeous in the latter.
