Last night I went to see Only Lovers Left Alive. A vampire love story starring Tilda Swinton and Tom Hiddleston as the vampiric couple. Try and imagine two better actors to be immortal, charismatic predators. The casting overall was pretty stellar actually. It's not a large cast, but everyone turns in a good performance.
So yeah...Tilda and Tom star as Eve and Adam, two vampires in love who reunite in Detroit to rekindle their love. It's...hard to describe the plot because it's very low-key and character-driven. It's not at all what you're expecting in a vampire flick -- the vampires raid blood banks and not necks most of the time and care about humnaity even if they're frustrated by them sometimes.
Frankly -- this is the Toreador Vampire LARP you've always wanted to play in. It's charming and delightful and surprisingly tender. I rather liked it and you should give it a look.
