I think franchises like The Matrix and Back to the future could have strong possibilities especially if they are more serialized. All new characters for BTTF though. So honestly pretty much a reboot of Quantam Leap, time travel is always an easy sell. I enjoyed the game that was made recently from Tell Tale, there's still a lot that could be explored.

Also something I think that would do great and honestly surprised they didn't try would be Inception. It honestly screams tv series. Especially if it's also simple extractions or episodes where you don't know it's a dream, or characters stuck in different stages, or even just the architecture. There are really a lot of great story ideas that it could go with.

Escape from New York: Great premise of simply using New York as a free for all prison with a lot of different sectors, as well as the government that created it (Trump's "wall" idea makes this an even more relevant storyline), and Snake Plissken is a great character.

Harry Potter should be re-done as a TV series in a decade or two.

Master and Commander might be a good one to try now, what are there like 21 books? Same with The Bone Collector, I understand that NBC is trying it again this year.
