Alongside all these ghosts and zombies the festival also has an Anima't category, showcasing animations from around the globe. That section opens with Japanese anime film Tekkonkinkreet, directed by Michael Arias.
The Hong Kong-based police thriller Eye In The Sky, directed by Nai-Hoi Yau and produced by Johnnie To, opens the Orient Express programme of Asian films.
The festival's Catalan Focus programme is a retrospective of famous films from Catalonia. Cine Regio, a Catalan organisation that unites filmmakers and distributors from various European regions (rather than countries), will foster networking opportunities.
Running until Oct 14, the entire festival is dedicated to the 25th anniversary of Blade Runner - Rutger Hauer and various members of Ridley's Scott original production team will be on hand in Sitges.
