Life On Mars is the smash-hit cop show starring John Simm as a detective who is involved in a car accident and wakes to find himself transported back to 1973 – a world dominated by Ford Cortina's, sheep-skin jackets and very hard coppers. In his new state of altered reality, Sam must prove himself to 'new boss', the hot-headed DCI Gene Hunt, all the while unsure whether he is awake or dreaming.
