Clash of the Titans is littered with household names from Gemma Arterton to Sam Worthington and the stars turned out for the World premiere in london.

Many, including Mads Mikkelson, had not even seen the finished article and were looking forward to seeing the 3D spectacle.

Having filmed much of the movie in green-screen and with the late decision by the studio to make it a 3D release, the cast were excited on the red carpet to see the finished product.

Cameos in the film include gangster movie actor Tamer Hasan and up-and-coming British star Luke Treadaway.

It also stars two of the UK and Ireland's biggest acting names of the last 20 years, Ralph Fiennes and Liam Neeson.
