Kiefer Sutherland fought back tears as he wrapped hit show 24 - because leaving the series after nine years was "much more difficult" than he anticipated.
Bosses at U.S. network Fox announced last month (Mar10) that the action show's current eighth season will be its last.
Sutherland recently filmed his final scenes as Jack Bauer - and it was an emotional moment for the star.
He tells Britain's Friday Night With Jonathan Ross TV show, "It's been the gift of a lifetime. It's a bittersweet situation. We believe it was right to end the series but we were not prepared for the emotional reaction. We worked with the same people for 14 hours a day, five days a week for nine years and they become like your family. I spent more time with them than my family.
"The very last day, it was hard shooting it and the second they called the last wrap I watched really tough guys fall apart. It was really moving. I thought I had prepared for it, I went to say a few words to the crew about how much this time had meant to me and my bottom lip went - as much as you think you can prepare for a moment like that it was much more difficult than I thought."
But the star is delighted with the ending. He adds, "There's a very touching moment. I don’t think me or the other actor thought it would be. That last moment actually worked well, we’re proud of it and it worked really well."
