AICN isn't exactly known for its accuracy. Need I bring up how easily they were suckered by those ridiculous Batmobile pics, which they believed were real, at first? Nevermind the Angel season premiere, which Herc got a supposed summary of, which he was EFFUSIVE about. Then when it was proved to be false, he then went on about how it was OBVIOUSLY a fake (Funny how he didn't think that the day before when he thought it was real) and was ticked off about how far it got spread across the internet (though it was AICN who was mostly responsible for spreading it, with Herc's reviews).
Having said that, I'm having a hard time believing Millar, too. Well, we'll see either way. Although I'm hoping Caviezel gets the part, since I think he's a great actor.
