Wow, I'm impressed. This trailer makes it look like they're avoiding a lot of the pitfalls of converting anime/manga to live action. I do appreciate the fishman. They look ugly, but not terrible for their setting. The actors are delivering their lines well. For me, the scars of Cowboy Bebop are still there, but I'm starting to believe I should trust this.
Still, and maybe this is just a nitpick, in that last scene withe the bounty posters...why Bellamy? Yeah, there's a few there but Bellamy's is front and center, if not a bit worn down. There's no way this series gets that far even if it's a hit. Why shown him then? Sure it could just be a reference, but it's weird they pick a Grandline pirate from later in the series when there's at least a few East Blue pirates to pick from.
