It was one of the internet's early memes, an apparently authentic classified ad from a local Seattle newspaper asking for volunteers to travel back in time with the author.

Its stipulation: "You'll get paid after we get back. Must bring your own weapons. Safety not guaranteed. I have only done this once before."

In the smart and often hilarious Safety Not Guaranteed, three disaffected Seattle magazine writers see the ad and then decide to hit the road to try to get to the bottom of the bizarre proposal. Eventually they find their guy, but begin to realise that perhaps he's not as batshit mental as he first appears. Or at least no more than they are.

Starring the suddenly everywhere Aubrey Plaza, the film is a remarkably accomplished feature debut from director Colin Trevorrow and writer Derek Connolly. It's currently in cinemas and should be considered essential watching for anyone who: a) believes in time travel  or b) believes in Aubrey Plaza.
