Alexa Davalos stars as Princess Andromeda in the 2010 version of the action epic Clash of the Titans. Davalos is no stranger to action films (she starred opposite Vin Diesel in The Chronicles of Riddick), and playing opposite a Kraken that wasn't there just meant she had to put her imagination to good use. "You know what? It's a funny thing. I think the first time I did it I was completely uncomfortable with it and thought, 'Oh, what am I going to do?' And then you kind of remember being a kid and you remember scaring yourself, or thinking there's something under your bed. You know, you go into the child inside of you," explained Davalos at the LA premiere of Clash of the Titans. "What we do is make-believe, you know? And so in its purest form it really is about the imagination and so I really enjoy it."
