Life On Mars creator Matthew Graham has revealed that the show will return for a concluding mini-series.
The show starred John Simm as a policeman in the present day who, after being involved in a traffic accident, 'wakes up' in 1973 to find that he is now working under DCI Gene Hunt (Phil Glenister).
Life On Mars ran for two series and had an ambiguous ending, with viewers left uncertain whether Simm's character Sam Tyler had died or not in the present day.
A follow-up series called Ashes To Ashes, set in the 80s and starring Keeley Hawes as a female detective in a similar predicament, ran for three series and brought back Hunt but not Tyler.
Talking to fans on Twitter, Graham outlined plans to produce a "final chapter" to the saga, writing: "It'll be set partially in the 70's, partially in the 80's and mostly in an alternate NOW.
"We would never make another Mars unless we really had something to say and could push the envelope all over again. Finally we have something.
"We are seeing it as 4 or 5 episodes and then done."
The final episode of Ashes To Ashes, which aired in 2010, hinted that both shows were set in the afterlife, with Hunt serving as a shepherd for recently-killed policemen and women in the present day.
