April 12, 2007: So. Wow.
According to Anime News Network and Variety.com, Nikkatsu Corp. announced it has greenlit LIVE ACTION movie adaptations of both Gatchaman and Yatterman. Yatterman is slated for a spring 2009 release date and will be directed by Miike Takeshi, with character and mecha designs by Katsuya Terada. I'm not sure if this is just for Yatterman or both films. For now, the info seems to be mostly about Yatterman. I didn't see explicit information about it, but I'm assuming this is a Japanese-language movie release only.
This live-action film should not be confused with Imagi's CGI Gatchaman movie (projected for 2008/2009) that I've been describing up til now.
And as a side note, I saw Imagi's TMNT recently, and I really enjoyed it. I don't know anything about the Teenage Mutant Ninja Turtles, but I loved the characters, and this film made me want to go buy the comic. Friends who were fans of the comic assured me that the property was treated very well. I think if Kevin Munroe and Imagi do for Gatchaman what they did for TMNT, we'll be seeing a great movie in 2008.
