tokyo zombie!

I must see this movie:

Mitsuo and Fujio - Japanese cult icons Tadanobu Asano and Sho Aikawa - are a pair of zero ambition slackers employed in a fire extinguisher factory whose only goal in life is the perfection of their jiujitsu wrestling skills. When a confrontation with their boss leaves the nagging executive dead they opt, of course, to take the easy way out and dispose of the body on the slopes of Black Fuji, a monstrous heap of garbage rising in the midst of Tokyo. But whether by the influence of toxic chemicals, black magic, karma or a mixture of all three, the muck of Black Fuji brings their boss back to roam the earth as a voracious zombie, unleashing an undead apocalypse upon the world. Before long the surviving humans are forced to live in a walled city where Fujio makes a living entertaining the upper classes using his jiujitsu skills in human versus zombie cage fights.
