Here's a big bonus.
In 2007, Matsumoto Hitoshi wrote, directed, and starred in the film Dai-Nihonjin (Big Man Japan). The film is actually a fake documentary with Matsumoto being interviewed by an off-screen cameraman most of the time.
Matsumoto portrays a fairly ordinary Japanese citizen who has inherited the extraordinary ability to grow several stories high and fight monsters which attack Japan. The film has several bizarre fighting scenes between Matsumoto and the monsters.
I thought the film was a bit slow. It's got a 6.3 rating on IMDB.
