Elizabeth Berkley & Kyle MacLachlan, Showgirls
Elizabeth Berkley and Kyle MacLachlan heat up this flick in what remains the highest-grossing NC-17 film of all time. Released in 1995, this Paul Verhoeven film has gotten mixed reviews over the years, but this scene stands out to anyone who saw it in theaters. You cannot forget a film like that!
Ben Affleck & Rosamund Pike, Gone Girl
In this murder mystery, Pike's character—a crazy person married to Affleck's emotionally distanced character—decided to seduce another man. Things got steamy a little too fast, but it all ends in tragedy when she cuts his throat open with a knife. The entire film is a rollercoaster of "whodunnit" right up until the very end, and it will shock you...
