Of course, there’s been theories making the rounds online that Nolan’s upcoming Tenet could be connected to Inception in some way, but we’ve now heard from our sources – the same ones that told us National Treasure 3, Now You See Me 3 and Extraction 2 were in the works before any of them were officially announced – that Nolan may have softened his stance about returning to the well, with an Inception spinoff reportedly in the early stages of development.
According to our intel, the proposed follow-up will take place in the same world but focus on different characters. And while the hope is for Nolan to direct it, he might end up letting his brother Jonathan get behind the camera and only help out in a writing and producing capacity.
