A new trailer has gone live for Big Man Japan, an independent movie about a Tokyo slacker who finds himself transformed into a stick-wielding giant entrusted with defending Japan from giant monsters.

Before you say, "Oh, that old story again," check out the video, after the jump.

A middle-aged slacker living in a rundown, graffiti-ridden slum, Daisato has a job that involves being shocked by bolts of electricity that transform him into a stocky, stick-wielding giant several stories high who is entrusted with defending Japan from a host of bizarre monsters. But while his predecessors were national heroes, he is a pariah among the citizens he protects, who bitterly complain about the noise and destruction of property he causes. And Daisato has his own problems: an agent insistent on branding him with sponsor advertisements, an Alzheimer-afflicted grandfather who transforms into a giant in dirty underwear and a family who is embarrassed by his often cowardly exploits.

A wickedly deadpan spin on the giant Japanese superhero, Big Man Japan is the sixth film in Magnet's "Six Shooter Film Series," a series of six films highlighting the vanguard of genre cinema from around the globe. Big Man Japan opens in March 2009.
