Rita (Laura Harring) in Mulholland Drive (2001)
On keeping it mysterious:
This movie's surreal atmosphere combined with the perplexing background of Laura Harring's vulnerable, wide-eyed, red-lipped enchantress Rita (no last name needed) keeps you guessing until the very end. Of course, a true femme fatale never gives it all away up front.
She always leaves you wanting more.
