Life on Mars and Ashes to Ashes co-creator Matthew Graham has promised that all the loose ends from both shows will be tied up in the final season of the spin-off series, airing next year.

Speaking to Digital Spy, Graham said that "the idea is to unify the two shows... By the time you get halfway through series three of Ashes To Ashes, you will actually feel like you're watching series five of Life On Mars!"

Graham also confirmed that there are no plans for a further spin-off from Life on Mars, stating bluntly that "I've written the last ever lines I will ever write for Gene Hunt. There's no way we could do another series after this. There would be no mystery left."
