Monster-slaying movie Clash Of The Titans is set to have its world premiere, with stars including Sam Worthington and Gemma Arterton taking to the red carpet.
The 3D epic sees Worthington take on the role of Perseus, the son of Zeus.
The 33-year-old Australian actor, who starred in Avatar and Terminator Salvation, trained six hours a day for two months to get in shape.
As a sandal-wearing sword-wielding man-god, he leads a daring band of warriors against monsters, demons and beasts.
He is helped on his way by former Bond girl Gemma Arterton, 24, who plays the part of mysterious spiritual guide Io.
The film, directed by Louis Leterrier, also stars Ralph Fiennes as Hades, the vengeful god of the underworld, and Liam Neeson as Zeus, king of the gods.
The world premiere will take place at the Empire Leicester Square in central London and the film, rated 12A, is set for release on April 2.
