Valerian teaser- sci-fi from a legendary director

Luc Besson has had plenty of hits including Leon and The Fifth Element but the 21st century had marked a pretty dry spell for the filmmaker, apart from those naff Arthur and the Invisibles animated flicks.

Then he was back suddenly and in a huge way with action sci-fi Lucy starring Scarlett Johansson and it seems he's keeping up the pace with another huge film getting close to release.

Valerian and the City of a Thousand Planets is adapted from the French comic book series Valérian and Laureline and is the biggest film Besson has made by far, with a budget close to $200 million.
