The website This is Infamous has a new report up claiming that Marvel has tired of trying to convince Joaquin Phoenix to take the role of Doctor Strange and have offered it up to Ethan Hawke.
Now, this is the same website that told us Boardwalk Empire's Jack Huston was up for the role less than five weeks ago and then Huston signed on to Ben Hur. So definitely take this rumor with a grain of salt.
According to their source, Hawke was offered the part last Friday and accepted it over the weekend but an official announcement is being held off (most likely for New York Comic Con). The 43 year-old actor is around the same age as Robert Downey Jr was when he took up the role of Tony Stark / Iron Man and Hawke has worked with Doctor Strange director Scott Derrickson previously on Sinister. So the rumor makes sense, but with so many names having been tossed around, I'll be skeptical until I see someone wearing the Eye of Agamotto.
