It was recently announced that Syfy had decided to remove the Battlestar Galactica spinoff from its schedule with immediate effect.
Series star Esai Morales (Joseph Adama) wrote: "I had an amazing time working on Caprica. We leave one we can stand behind. I'm humbled and honoured by your words of support and appreciate every one of you who've reached out to me."
He added that fans "will not be disappointed in the events leading up to the Caprica finale".
His co-star Sasha Roiz (Sam Adama) commented: "[Working on Caprica] was a wonderful experience that I will always cherish. I'll miss Sam and the world we created. Thanks again for following and supporting."
Composer Bear McCreary and celebrity fan Simon Pegg also used Twitter to blast Syfy's decision.
McCreary wrote: "RIP Caprica. So frustrating that it's cancelled right when the story arcs get really tight. Those last 6 eps are the best of the series."
"Sad to hear Caprica got cancelled," agreed Pegg. "Shows just aren't given the opportunity to hit their... stride these days."
The remaining five episodes of Caprica will air on Syfy in the first quarter of 2011.
