Are you telling me you made a time machine out of a DeLorean?! Simply great storytelling here in a knotty, brilliantly constructed time travel-adventure-comedy that has a great big throbbing heart bursting with love at its centre. When you consider it came from the wickedly funny minds of Roberts Gale and Zemeckis – remember the amazing Used Cars?! – it seems an even bigger achievement. Marty McFly (Michael J. Fox) is an average teenager in Twin Pines, a small town with a nice square boasting a clock that hasn’t worked since 1955, a cinema running soft porn, and screwed up parents with an alkie mom (Lea Thompson), a meek dad (Crispin Glover), loser sister and a thirty year old brother in a MacJob. He has a cute girlfriend, a skateboard and an eccentric friend called Doc (Christopher Lloyd) a scientist who has wasted his family’s fortune making a ‘flux capacitor’ fuelled by plutonium. Just when the nutty professor manages to prove he can travel back in time with an Eighties sports car (to die for!) the Libyans come calling and when Doc is mown down in a hail of gunfire Marty guns the engines of the DeLorean and at 88mph is catapulted back to the week the town clock stopped working in a lightning storm. He’s initially mistaken for a spaceman and finds that his housing estate is only just being constructed. He needs to ensure that his parents get together in high school or the future will look very different as he and his siblings’ images begin to disappear from the family photo back in 1985 and Marty’s mom begins to fall for him in one of the more brilliant takes on incest in film history! Plus he has to get back to 1985 to save Doc’s life in what is literally a race against time! … Fast, sharp-witted and brilliantly inventive, this has the kind of gleaming detail (skateboards, digital watches, Diet Pepsi, puffa jackets for 1985; Davy Crockett, sci-fi comics, a classic diner, a Barbara Stanwyck oater at the movie theatre for 1955) that makes it almost documentary-like in resonance and relatability. The organisation of the narrative is mind-boggling when you consider the complexity of the story elements. Add in hugely likeable stars, great one-liners, and a genuine sense of fun, this is proof that you can rewrite history and even get some very subtle revenge on the school bully! One of the cinema’s evergreen classics, this is tonally perfect: it just sings with joy. Brilliant.
