The Official Fist of the North Star movie site has been updated with a teaser in flash at the trailer section. The Japanese title "真救世主伝説 北斗の拳 ラオウ伝 殉愛の章" (Hokuto no Ken - Raoh Gaiden Junai-hen Arc ) is translated as Fist of the North Star - Raoh Side Story Junai Arc. As reported previously here, this movie is part one of the Hokuto no Ken - Shin Kyûseishu Densetsu (Fist of the North Star - New Saviour Legend) trilogy. It will be theatrically released nationwide in Japan by Toho in the March of 2006.
As a long time fan of this series, I'm very excited to check this badboy out. The animation looks better than ever. Anybody who is clueless about this anime/manga, go here for a detail explanation about the plot but just so you know, this site contain spoiler.
