Mirren is sexy and nude what a body. Got great legs too!. of course the nudity is alot like the movies at this time very fleeting, and her romp in bed astride him doesn't last like Basic Instinct or Madonna's film in the late 80's early 90's, Nudity was limited to sexplotation or ahardcore pretty much until 90's. but it does give a view what she looked like before she made Caligua years later.
shareCaligula was made the year before.
shareCheck out Ken Russell's superb film SAVAGE MESSIAH (1973, seven years before HUSSY), where her nudity is far from fleeting. She takes the lead character on an extended tour of her family mansion in her birthday suit (she, not he). Plenty of time to ogle! This was as extreme as Russell went in this film, which is why it's one of the few Russell films that critics generally liked. Also, as I recall, she pretty much performs in nothing but a body stocking throughout A MIDSUMMER NIGHT'S DREAM, a few years earlier. Both films are well worth seeing!
Oh, and of course, you'll also want to check out her feature debut, THE AGE OF CONSENT, where she poses nude for artist James Mason. All three films will make the Mirren fan very happy!
