Series star Joshua Jackson (Peter Bishop) recently hinted that the series could continue "off network" if Fox declines to recommission it.
"I think there's a possibility that if people just watched the show on the day and date, and if the numbers came back, [renewal] is a possibility [on Fox]," he said. "[But] the TV landscape is a different place than it used to be, so [cancellation on Fox] might not be death."
Fringe continues on Fridays at 9/8c on Fox. Sky1 airs the show on Wednesdays at 10pm in the UK.
