The end is finally nigh for NBC's Timeless, which will wrap up with a two-hour TV movie later this year — which comes after the series has actually been canceled twice (once after Season 1, then after Season 2).

Speaking to Collider, series co-creator Erik Kripke (screenwriter of The House With a Clock in Its Walls) offered some of the first information on what viewers can expect from the finale, stating that it's basically two episodes mashed together.

"As a matter of fact, we tried, at one point, to do one long historical period to last over two hours, and then eventually [producer] Arika [Lisanne Mittman] wisely said, ‘Why are we doing this? Why don’t we just do what we always do, which is spend an hour in two different time periods?’ And so, though they’re connected and though it’s one long mythology story that plays over both, they really are, in effect, two time periods of Timeless that they visit, and we’ll shoot each one. We shot eight-day episodes, and this will be a 16-day shoot. It will be exactly like two more episodes of the show," he said.

As for closure, fans need not worry, because the finale will wrap things up quite nicely for our beloved time travelers. But hey, you never know what other network or streamer might be interested in more stories with these characters, which is why the movie won't close the door forever.

"There’s a certain amount of shocking turns, and we tried to let it build to something and provide a certain amount of closure, and give you a sense of where these characters go. We tried to put a period at the end of the sentence, but not so much that the door isn’t open for further adventures, down the road," Kripke continued.

The Timeless movie will air on NBC sometime in December.
