But will he also be suiting up as the Green Goblin? We’ll have to wait and see, but The Hollywood Reporter has confirmed that the actor, who recently appeared in The Town and The Muppets, has joined the cast of The Amazing Spider-Man 2 as Norman Osborn. The site says that it is currently unclear whether or not he will suit up as the villain in this movie or the sequel, but adds that “Osborn starts out as a mentor to the superhero before turning bad.” Cooper is an Academy Award winning actor who is no stranger to playing the villain and this news more than likely confirms speculation that Colm Feore will play J. Jonah Jameson. Director Marc Webb has previously said that he would like to adapt “The Gwen Stacy Saga”; a storyline which saw Gwen Stacy die at the hands of the Green Goblin.
