So here we are. The final episode of Life On Mars (tonight, BBC1, 9pm) is upon us, and what an episode it is. The brilliantly original, brilliantly acted and brilliantly brilliant series has been a breath of fresh air during the two years it has been with us. Now it’s all over.

Last week I was very lucky to be invited to the cast and crew wrap party, and while I was there I was even luckier to persuade Dean Andrews, who plays Gene Hunt’s burly, no-nonsense sidekick Ray, to have a few words with me about the final episode. Here he is!
