Maybe I just assumed it was Sarumon and it wasn't. I don't tend to watch all the extras with the show runners so I missed that. He certainly seemed to e Sarumon the way he calling Gandalf old friend, etc. But, maybe he isn't. If he's not that I withdraw my criticism of that, but change it to say they should have done a better job of making it clear that it was not Sarumon. As Tenordas noted, he looked like a younger Christopher Lee from the Peter Jackson movies and the staff looked similar. But I guess that's my bias based on watching the Peter Jackson movies over and over again.
