British actor Idris Elba takes on a significant role in Ridley Scott's new sci-fi thriller, Prometheus.

Elba told Talking Movies' Tom Brook the film is not a prequel to Scott's 1979 film classic Alien - but more a tale of mankind's origins.

Talking Movies is broadcast on BBC World News on Saturday at 13:30 GMT and is repeated on Sunday at 00:30, 07:30 and 20:30 BST.
