Warner Bros Japan is streaming a "special preview" for Studio 4C animated film
Berserk Golden Age Arc I: Egg of the Supreme Ruler (Berserk Ougon Jidaihen I: Hao no Tamago, ベルセルク 黄金時代篇Ⅰ 覇王の卵) which contains a blend of CG animation to represent the swordplay combat scenes. Any fan of Kentaro Miura's ultra-violent manga
Berserk will tell you that Guts wields a big-ass sword and the length of his blade is equally matched by his unparalleled capacity for berserker rage so if any poor bastard dares mess with him, they can pretty much kiss their ass goodbye. As you can see in this bloody clip, some of the Hawks' soldier learn that lesson the hard way.
The theatrical release date in Japan is on February 4th. You'll find the clip embedded below
