Farrell loves playing 'powerful, timeless, erotic' vampire

Colin Farrell would like to play a unicorn, but feels a vampire is more realistic.

Farrell currently stars as vampire Jerry in a remake of classic 80s movie 'Fright Night', and he admits the blood-sucking creatures appeal to most people because of the mixture of "mythical" with human form, although he "wouldn't mind" mixing thing up and playing the one-horned fantasy creature.
