UPDATE: Toei and Shueisha have officially confirmed this as fake, so don't panic…yet. http://www.animenewsnetwork.com/news/2016-06-16/live-action-one-piece-film-plans-announced-by-chinese-company/.103295
Chinese company Sanghai Minghuan bought the rights to make a live-action One Piece film for $15 million. Masataka Kubota has been cast as Luffy and Xie Leilei has been cast as Purin. Yes, Purin. If she's later revealed to be an antagonist and ends up in this movie as a protagonist I will laugh so hard.
Well, if this does end up panning out, let's hope it doesn't have the same effects as Dragonball Evolution and the 4Kids dub.
