I was first exposed to Tetsuya Nakashima's filmmaking not through the internationally-acclaimed MEMORIES OF MATSUKO (which I was absolutely in awe of), but through a brilliant short film by him done quite a few years ago (could be 2004 or 2005, not sure), ROLLING BOMBER SPECIAL, which starred SMAP's Katori Shingo and totally makes fun of the Super Sentai (Power Rangers, Masked Riders etc.) genre.
This short film is a MUST-WATCH.
