Lucy (out today) is the new film from Luc Besson. It is the stupidest film you will ever see, but that's by-the-by, what actually matters is that it contains many of the elements that we know, love and recognise as being a part of Besson's arsenal of familiar movie tropes. Yes, as a film-maker, Luc doesn't stray too far from his tried-and-tested, crowd-pleasing methods (until the end of Lucy, anyway), so to celebrate his unwillingness to deviate from the fail-safe, we thought we'd celebrate those tropes and make sure you're aware of the ten ways you know you're watching a Luc Besson film.

Oh, and when we say 'a Luc Besson film' we're talking about films he's either written or directed...
