Apparently Michael Massee has been cast in an unspecified role in the upcoming, Marc Webb-helmed Spiderman reboot, according to IMdB. While not being the most trustful news source, and the fact Mr. Massee was not seen on the set of the film, this is still an interesting turn.
Massee is a renown actor in such movies and TV shows as the Crow, Revelations, and more recently Flashforward. he's mostly cast in villainous roles (such as Funboy in the Crow and Dyson Frost in Flashforward), but it just might be a small cameo or something like that. if he IS actually playing a big role, keeping his resume in mind, let's think for a second about what roles can he play.
-first off, it could be just a small cameo to reference his earlier work with comic-book movies, like the Crow and (ugh) Catwoman, or a small role like Thomas C. Howell's role.
-secondly, pretty recently we have seen pictures of Peter with an Oscorp tag and of course, the Oscorp logo itself was shown. there was no implication of either Norman's role, or if he was casted, except from the rumored storyline a few months ago, which was reported to be pretty close, so what if he's playing Norman Osborn?
he's in the right age, he looks kinda like him and also has a resemblance to Willem Dafoe. this also explains why he wasn't seen on set, as possibly the only places we see Norman are in the Oscorp builing. though there is a character very similiar to his role in the TV miniseries Revelations... that might tend to be a little more psychotic.
he was a reiminscent of Kassady in that series, and shown that he can play very insidious, psychotic characters. but what if he'll rather play an old, forgotten enemy of Spiderman?
he looks exactly like Smythe, and also already kinda was Smythe in Flashforward. just a personal guess, but probably way too much of a stretch. my 2 cents are either Norman Osborn or a cameo, but everything's still in the air.
