Dennis Hopper is so good in that movie; I remember hearing about his death at the Golden Globe Awards Ceremony, it was so sad, such a good actor.
His roles in Apocalypse Now and Blue Velvet are unforgettable.
P.S.: David Lynch and Kyle MacLachlan are so good, Twin Peaks best thing ever.
Edit: That movie (Blue Velvet) can turn anything creepy, haha (Roy Orbison's "In Dreams" for example).
Edit 2: Almost forgot to mention, that scene where Dean Stockwell (Ben) lip-synchs to "In Dreams" is mesmerizing, he did SO GOOD.
