I'm not a Morning Musume fan, and really only know this because I'm a big Super Sentai fan, but Haruka Kudo, formerly of Morning Musume, is now pursuing an acting career and will be one of the main characters in Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger. She will portray LupinYellow. Well, who knows? If I like her enough in the show I'll probably have to look up some of her idol performances. I wonder if she'll do any songs in the show?

Also, if anyone wants to follow the show with English subtitles, I recommend TV-Nihon: http://www.tvnihon.com/
They probably won't be the only fansub group that translates the show, but they're certainly my group of choice.
