Time is sadly up for Timeless.

Studio Sony Television has failed to find a new home for the sci-fi drama that was (twice) canceled by NBC, so that's almost certainly the end of the line for the cult favorite, according to the show's co-creator.

"@SPTV has notified @TheRealKripke and me that efforts to land #Timeless at another network have sadly failed," co-creator Shawn Ryan shared on Twitter Monday. "While Sony will continue to look at any and all options, actor deals have expired and it appears there will be no Season 3 or beyond. "

"Discussions still take place between @SPTV and @NBC about a possible 2 hour movie to conclude the #Timeless story, but there are considerable economic obstacles that make it an uncertainty," Ryan added. "We will update you when we know more."

Ryan thanked the show's loyal #ClockBlocker fans for the support that got the show brought back for a second season after getting canceled after Season 1, and who held out hope for Season 3.

After Timeless ended Season 2 on a cliffhanger, fans have been clamoring for a movie to bring closure to the story, but it's a long shot at this point.
