Similar movie - 'The Witches Hammer'
Fans of 'Razor Blade Smile' should check out 'The Witches Hammer' (2006). It's a low budget British movie about a young woman who is attacked and vampirized, and subsequently press-ganged into becoming an assassin for the British Intelligence services.
It was recently released on Region 2 DVD. I bought it because I'm a huge fan of 'Razor Blade Smile' and 'The Witches Hammer' seemed to be in a similar vein (no pun intended). I wasn't disappointed. Although it's not quite as entertaining as 'Razor Blade Smile', it's still a very enjoyable low budget horror/action flick. Highly recommended.
