Sir Ridley Scott has told BBC Radio 5 live that his new film Prometheus is not a prequel to his 1979 hit Alien.

Speaking to Simon Mayo and Mark Kermode, he said that even if the character of the Space Jockey was present in the sci-fi franchise, although never formally introduced, this new film was not directly linked to it.

Sir Ridley explained why he was revisiting the genre after more than 30 years.
