This week, Collider got a chance to catch up with Michael Sheen at the press day of a film that weâll be writing about later. However, since we also got a catch to ask him about working on the two-part The Twilight Saga: Breaking Dawn, we wanted to get that portion of the interview posted right away. Sheen revealed that he got the opportunity to delve into Aroâs insanity a bit more, this time around, and that he got to show more of whatâs under the surface of the character. He also talked about how much he enjoyed working with Bill Condon and thought the director handled the huge undertaking of a two-part film with about 40 new characters and a huge battle scene brilliantly.Sheen also stated that, while he was talking about doing a role in Dark Shadows, the announcement of his involvement was a bit premature, and he will not be doing that film. Check out what he had to say after the jump.What can you say about what youâll be doing in The Twilight Saga: Breaking Dawn?MICHAEL SHEEN: Itâs the same part that I played before â Aro. Was there anything you got to discover in playing him this time around, that you hadnât learned the last time you played him?SHEEN: Heâs more of a presence in these films than he was in New Moon, so I got to explore the character a bit more and probably fleshed it out a bit more. I donât think that thereâs anything that I learned. I just was able to go into the insanity of the character a bit more. I got to show whatâs under the surface a bit more this time, which was fun. How was Bill Condon to work with, as a director?SHEEN: Bill was wonderful. He was terrific. Heâs a very, very friendly, warm person. He obviously has a very varied and interesting body of work, and brought that to bear. He made everyone feel very comfortable. It must be quite hard, coming onto a film where people have already been together for a long time. Each film is a different director and you think, âWhatâs this one going to be like?â But, everyone really warmed to him and thought he was terrific. I think he did a really good job. It was a huge organizational thing. We had something like 40 new characters being introduced in this film, and the big battle scene took about four or five weeks to film. It was a huge undertaking, and he handled it brilliantly. When a new director comes on and you already know the characters from having done previous films, do you feel like you know the characters more than the director, or does each director really bring something new out of you?SHEEN: Personally, I was only on New Moon for two weeks, so itâs not like I got used to it. But, for the other actors, thereâs probably a wariness about, âIs this person going to come along and not really get what it is weâre doing, or are they going to try to change it too much?â For a director coming on board, I would imagine thereâs the pressure of wanting to make your mark and be different to what other people have done, but at the same time, not wanting to go against the flow of the whole series. I would imagine itâs quite a difficult balance to strike, but everyone seemed very happy on it and seemed to enjoy working with Bill. What are you going to be doing in Dark Shadows?SHEEN: Iâm not in Dark Shadows. Was that just misinformation?SHEEN: No, it was something that got talked about, but itâs not happening. It was a bit premature.
