The cast of Terry Gilliam's The Zero Theorem spoke of their wariness of technology, ahead of the fantasy/sci-fi film's premiere at the Venice Film Festival last night.

The film is the tale of a reclusive computer hacker, played by Christoph Waltz, determined to discover the reason for human existence.

Director Gilliam compared it to his cult classic Brazil, for its futuristic themes.
