Here's an exclusive look at the "Leaping Monster" that terrorizes Tokyo in Big Man Japan, the bizarre superhero movie coming to U.S. theaters on May 15. Click through for the Japanese drawings of the monster.

Another exclusive image is the photo of Big Man Japan IV, the grandfather of the current Big Man. According to the film's official synopsis:

A middle-aged slacker living in a rundown, graffiti-ridden slum, Daisato's job 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 an outrageous portrait of a pathetic but truly unique hero.

BIG MAN JAPAN is the fifth film in Magnet's "Six Shooter Film Series," a series of six films highlighting the vanguard of genre cinema from around the globe. Also included in this series are: LET THE RIGHT ONE IN (Sweden), SPECIAL (US), Nacho Vigalondo's TIMECRIMES (Spain), Ollie Blackburn's DONKEY PUNCH (UK) and EDEN LOG (France).

We reviewed the movie here. And as I mentioned, it's in select theaters on May 15.
