The first on-set footage of Sam Worthington, Gemma Arterton and co. on the set of Clash On The Titans has now arrived, and while there is of course no CGI yet, it certainly looks like they’re going for some full-on, over the top action as Perseus battles to save Princess Andromeda. We’ve embedded two videos below. The first is MTV’s set visit, featuring interviews and behind-the-scenes footage, while the second is b-roll, giving you a further look at some of the stunts that MTV filmed. It all looks pretty epic and entertaining. The Louis Leterrier (The Incredible Hulk) directed Clash Of The Titans will be in UK cinemas on March 26th, 2010.
