He didn't know whether he was actually back in Time, in a coma, or had gone mad. So he tried to adjust to his new surroundings (where modern police methods were unheard of, and un-PC behaviour ruled the day) while still struggling to get back to the world he knew in 2006.
The first season - excuse me, series - ran for eight episodes and concluded with him being able to unblock childhood memories from that time period, thanks to him supposedly being actually back there in person as an adult.
'Life On Mars' will return for a second series next year, but the creators of the show have decided that it will also be the last for this fantastic show in order to preserve the credulity of what they created. Executive producer Claire Parker said the story would reach a "natural and explosive climax" in which viewers like you will learn how Detective Inspector Sam Tyler, played by John Simm, became stuck in the '70s.
The producers said two endings to the second series had been filmed "to keep everyone guessing until the very end." Writer and co-creator Matthew Graham said: "We decided that Sam's journey should have a finite life span and a clear-cut ending and we feel that we have now reached that point after two series.
"Although it is sad that we have just finished filming Sam's final scenes, it's also been an incredibly exciting few days."
Personally, I hope it turns out that he really did go back in Time somehow. It's just more in keeping with the "Toobworld lifestyle". Mainly I just want to find out that characters like DCI Gene Hunt and Officer Annie Cartwright really did exist. It's selfish on my part, of course. I want to be able to say that "the Gene Genie" is the uncle of Ash Morgan of 'Hustle' (who's played by Philip Glenister's brother Robert), and that Annie is descended from Adam Cartwright of 'Bonanza' after he left the Ponderosa to sail to England.
Over here in America, David E Kelley is making a pilot based on the show for US audiences. It'll be interesting to see if he can craft his version of 'Life On Mars' to realistically run for at least five seasons, considering American TV is geared toward the profitable goal of syndication where 100 episodes is the magic number.....BCnU!
