I think Conan is a sleeping giant of a movie or TV franchise, frankly. The issue with Conan has always been, who plays him in a live action setting? Arnold was perfect, but the reboot with Jason Mamoa fizzled. Conan with a surfer dudebro accent just doesn't work.
I think you need to find someone to play him with the right physicality. Maybe John Cena could pull it off. I don't think the Rock is the right guy, as he's too campy. But, who knows? Another possibility is Alan Ritchson. They are working on a Red Sonja project right now, so I think another Conan try is inevitable. If that works, then the Conan stuff goes up again.
