I don't know about you, but that sounds awesome. It certainly sounds better than both the 1987 He-Man adaptation, Masters of the Universe and the 1982 non-adaptation The Beastmaster, which I always thought of as a pre-He-Man He-Man movie (anyone else ever notice that Beastmaster 2: Through the Portal of Time has the same plot as Masters of the Universe?). Of course, neither of those movies would be hard to beat. Warner Bros. and producer Joel Silver could hire a monkey to write a better script.
Unless you're hoping to avoid spoilers, head over to Latino Review to read more praise and plot information for Grayskull (and weep for the omission of Orko). And after getting pumped up about that movie, keep in mind that Marks also wrote or co-wrote the scripts for the upcoming Green Arrow (formerly Supermax: Green Arrow), which IESB.net just reported is looking at a possible summer 2009 release date, Voltron and Street Fighter: The Legend of Chun-Li (for which we shared another Latino Review script review last year).
