That's not to say that "guy" isn't also on their list. Marshall has plenty of experience in movie-musicals, having helmed Annie, Chicago and Nine, while Murphy is the one responsible for turning Glee into one of the most popular shows on television right now. Mangold, too, has dabbled in music having directed the biopic Walk the Line -- and even Abrams has helped compose the themes for some of his TV shows. So, yeah, all these guys make sense for different reasons, and it seems like Universal wants to explore a number of unique ways they can attack the adaptation of one of Broadway's most popular musicals.
Wicked, of course, follows the relationship between Glinda the Good Witch and Elphaba, the green chick who eventually becomes the Wicked Witch of the West. The musical tracks them as little girls through the events of the Wizard of Oz and then after. It's a fun story, and one that was originally supposed to be a movie before Universal decided to make it a musical first. Now, with a number of other Oz projects in the works, the studio needs to make a move before there's too much competition, and also before audiences become sick of the property.
Out of those four guys, who would you like to see direct Wicked?
