[Vampyr]

I agree with Ginky.

The new dumbledore is going to have to be dumbledore for 5 movies. That's the majority of the HP series, so I think it's fair that he should be able to act like HE wants.

He cant spend 5 films acting like another actor acts.

But yeah, it is a minor part, like Null said. It's a major role, but a minor part, if that makes any sense at all. So it's not a huge deal.
