Rian Johnson goes behind scenes for Star Wars: The Last Jedi

He has been very clear that he no longer believes in the ways of the Jedi and he was expected to demonstrate other new way to use the Force in Episode 8.

So, why is he now shown in action with the Skywalker blue lightsaber ignited? Excitingly, it also looks like he is using other Force powers at the same time.

Is he fighting Rey, Kylo Ren, Snoke or the Praetorian Guards?
