Pretty much everything about David Lynch’s Blue Velvet can be classified as uncomfortable, but Dennis Hopper’s wonderfully deranged performance as flesh-and-blood monster Frank Booth is without a doubt the film’s creepiest component. He’s a wackjob who gets sexual thrills from dry humping while all hopped up on a mysterious, inhaled gas; he’s also the type of guy who beats his helpless lover, Dorothy (Isabella Rossellini), just for kicks.
Near the end of Blue Velvet, Dorothy shows up on good guy Jeffrey’s (Kyle MacLachlan) front lawn totally naked, but also covered in bruises and scared to death. Under happier circumstances, seeing Rossellini approaching your doorstep in the buff would be one hell of a joyous surprise. The wrath of Frank Booth, however, drains the sight of all its attractiveness
