German cutie Isabelle Menke has few credits, but they’re good ones. Even when she’s on stage, as in Hamlet (2002), she finds a way to get the cameras rolling and the action going. In this modern interpretation of that Shakespeare classic, Isabelle plays Gertrude without any clothes on. Ay, there’s the rub . . . and her bush! Isabelle was no stranger to nudity, having already appeared in the thriller Flick (2000), where her large breasts got a mam-handling from her man in bed. As good as both those perv-formances are, the explicit sex in Montag kommen die Fenster (2006) tops it all. This is an actress who will do anything for tart, ah, that’s art.
