Kagemusha (produced with the help of… Lucas 😉… yeah you all already know that), Stalker (never seen this one), Daimajin (don’t remember which one, all 3 are awesome and easy to find in bluray), Ran, Goyokin. Mostly japanese influences. We could easily add Akira for the stunning “dead silence” sequence and Lone Wolf and Cub (the second one) for the impressive throne room battle (or maybe another influence, yet it was screaming “Kenji Misumi” for me 😃).
(Kenji Misumi’s Ken and its Kendo philosophy might have influenced the training sequences, but I haven’t seen it in a decade so I’m lacking fresh memories about it)
(and Hayao Miyazaki - Princess Mononoke comes in mind - for the Crait ambiance with the crystal wolves and the FO walkers)
