Similar to Travellers

Before I watched the series traveller, I remember seeing a movie which could actually ne connected to the series.

Maybe from the future point of view, they trying to travel back, preparing the machine and team, something like that.

I don't have much besides the feeling they could be connected on a reverse point of view.

It's not looper, the adjustment bureau, invasion or predestination.

No one of these above fits travellers story.
