After 18 years in his role as Detective Inspector Jack Frost, Sir David Jason has bid farewell to the series.
And it was an emotional time for all, as he said his final goodbyes.
"You'd have needed a heart of stone not to feel emotional," the 70-year-old actor says.
"On the final day of filming there were moments in the script when I had to find tears and let's just say those tears weren't hard to find.
"I think everyone on set had the feeling something really special, which had been a big part of all our lives, was finally coming to an end."
The star, whose acting career has spanned over 45 years, said the time had come to end the show.
"We thought we've got to draw a line in the sand somewhere and if it's not this year it will be next.
"So we took the decision that Frost, unfortunately, would be leaving the Force and whether he just hangs up his hat or is carried out feet first remains to be seen."
The two-part finale, entitled If Dogs Run Free, will hit screens in April.
