Hey yo what's up guys, I'm Warmachine375, chat moderator and ever-helpful wikia contributor of Nanatsu no Taizai wiki. And also a devoted fan of my now favorite series after dropping Fairy Tail when it lost all its awesomeness I once rooted for since the old original FT anime :( (the 2014 FT anime sequel series sucks after its long hiatus and the manga chapters feels kinda meh until I discovered Nanatsu no Taizai through FT X NnT Christmas crossover special that got me into NnT in the first place XD)
Pass that aside well, I've been thinking, perhaps a little too early for a rising hot shounen series with a 100+ chapters and a 25-episode season (hope there'll be season two probably next year once there's enough material to adapt with no need of unnecessary fillers) but is there a possibility of a Nanatsu no Taizai anime movie with its original plot, new characters either based from Arthurian myths or Nakaba-sensei's limitless imagination, other countries, awesome other kinds of Powers and not to forget about some DBZ-style battles in it! It'd be awesome! XD XD
Though it may be a sort of taboo for anime/manga fans in my own perspective, but I always wondered if there's gonna be a live-action film version of Nanatsu no Taizai. You know in a European setting for the film (I'd take the setting where Game of Thrones is played there during production), a good selected cast of actors and the good balanced plot and all, not to forget the powers and battles. However since we received badly-adapted live-action anime films (like DB Evolution and The Last Airbender), I highly doubt it due to reasons us anime fans are aware of (bad directors and production staff) but it's imagination. It couldn't hurt to imagine it in our own minds right? Hehehe
Anyways, feel free to comment on your opinions about this topic and enjoy! :D
