Gemma Arterton insists 'Byzantium' is not another 'Twilight'.

The actress assures her new movie, despite being a vampire thriller, isn't like the hit franchise which focused on a romance between a blood-sucker and a human.

Gemma said: ''It's an art house horror. Its definitely lower key than your blockbusters like Twilight and its got much more of beating heart. Visually its beautifully shot. It's heavier, more adult.''

The film is adapted from Moira Buffini's play 'A Vampire Story' and follows a blood-sucking mother Clara and her daughter Eleanor (Saoirse Ronan) who seek refuge in a deserted guesthouse called Byzantium who turn the coastal town into a place of murder and darkness.

The horror is directed by Neil Jordan - who previously made the vampire movies ' Interview with the Vampire' and 'High Spirits' - and Gemma heralds him a ''genius in this particular genre''.

The British screen beauty has also just finished shooting 'Runner, Runner' with Justin Timberlake and Ben Affleck which is set to be released in September.
