Ridley Scott says Hollywood has exhausted the science-fiction genre.

The 74-year-old director has returned to space for his latest movie 'Prometheus', a prequel to his iconic 1979 movie 'Alien', but admits he has avoided other-worldly films because there have been so many.

Ridley - who also helmed 1982 cult classic 'Blade Runner' about futuristic human robots - said: "One of the problems with science fiction, which is probably one of the reasons why I haven't done one for many, many years, is the fact that everything is used up. Every type of spacesuit is used up, every type of spacecraft is vaguely familiar, the corridors are similar and the planets are similar. So what you try to do is lean more heavily on the story and on the characters, to give you lift-off."

'Prometheus' - which stars Noomi Rapace, Michael Fassbender, Idris Elba and Charlize Theron - has been shrouded in mystery since it was announced to be in production an cast members were only allowed to read scripts in Ridley's presence.

The movie will be released in cinemas in June and Ridley has already hinted he may shoot a follow-up.
