In the seventh movie, is Lord Voldemort played Von the same actor in the other Filme oder someone different, because he sounded different in the seventh movie trailer?

I'm pretty sure he's still played Von Fiennes.

No its not played Von a diffrent actor,it is still ralph fines because when i watched the trailer i looked at his face and it was still him and it was his voice as well.So Don,t worry its him.

i think its the same person
