Time flies. It's been almost two years since Richard Kelly's bravura head-scratching mood piece Donnie Darko was sprung on an unsuspecting world. A flop at the US box office but a sleeper hit in the UK, this time-travelling story about Donnie (Jake Gyllenhaal) - a troubled paranoid schizophrenic teen in 80s American suburbia - hit a post-9/11 nerve. Re-released in a Director's Cut with 20 minutes of additional footage, this extended Darko lightens the darkness, proving that - sometimes - less really is more.
