10 Complex Movies You Really Weren't Prepared For

Enemy, a film that is sure to have you scratching your head and asking everyone you know whether they've seen it, thrives on ambiguity. It wants you to question every little moment and every scene in order to try and work out what, exactly, is happening.

Luckily this is a movie directed by Denis Villeneuve, who brought audiences both Arrival and Blade Runner 2049, two of the decades' best films.

The plot starts out simply enough: Jake Gyllenhaal plays a quiet professor who, one day, stumbles upon a man who looks exactly like him. As the film progresses, the professor and his doppelganger are drawn together into a series of strange encounters, each one more disturbing than the last. Before long it's no longer clear who's out to get who... or whether these men are actually the same person.

Despite the film's complex nature, and a script that never dares to give too much away, Enemy remains a fascinating, compulsive watch: in the hands of a lesser director, it might have been frustrating. In Villeneuve's hands, it is simply mesmerising. And don't even get started on its now infamous, arachnid-inclined ending, which takes the movie into the stratosphere of "What did I just watch?"
