1. Donnie Darko (2001) Doe-eyed Jake Gyllenhaal starred in this classic teen brain-fryer (that's him there, being cuddled by someone called Jo Whiley). In short, it's about a loner given the chance to be a hero thanks to a parallel existence opening up. But writer/director Richard Kelly throws in a man dressed as a rabbit, a lady called Grandma Death and a load of wormholes just to confuse us.

2. The Matrix Reloaded (2003) The first one kept the premise simple - what if our world was just a computer programme? Enter the sequel and a load of waffling from some beardy called The Architect and a we lost the will to live.

3. Revolver (2005) Guy Ritchie can make gangster movies blindfolded. Trying to make a gangster movie that confusingly deals with spirituality, numerology and psychology proved a little more trying - for all of us.

4. Mullholland Drive (2001) Naomi Watts stars in this thriller from David Lynch, the king of big screen weird. I think it's about the shallowness of Hollywood - nutty Dave wisely says just forget the plot and enjoy the creepy atmosphere.

5. 2001: A Space Odyssey (1968) Old-skool sci-fi and still one of the best. Yes, it's about a spaceship's computer that develops a personality. But a load of prehistoric apes, a mysterious monolith and a giant embryo in space hint that it's also about our very existence. Mesmerizing.
