5. Seth Gecko (George Clooney)
Movie: From Dusk Till Dawn (1996)
Why Hes a Douche: This is an easy one. Seth is the kind of guy that thinks he should have whatever he wants, and hes not beyond killing, maiming and kidnapping to get it. Theres no higher level of douche-baggery. Admittedly hes not as far gone as his brother, but its implied in the movie that Richie is mentally ill; Seth doesnt have that excuse to fall back on.
Why You Love Him: If another actor had have played him, maybe you wouldnt have. As it stands, Clooney is perfect for this role, and oozes irresistible charisma throughout. Not only that, but there are at least thirty lines of dialogue throughout that I wish Id said instead of him at some point in my life. Im still looking for a way to work I may be a bastard, but Im not a fucking bastard in to a conversation somehow. Seth is a man of action, of words and of a stylishly raised eyebrow just before he pulls the trigger. Douchebags just dont come much cooler.
