Christoph Waltz was recently interviewed by German magazine Zeit-Magazin Mann. During the interview he expressed dissatisfaction with his portrayal of Blofeld. He also said he does not know if he will return in the role.
“I cannot claim that I’ve really nailed Blofeld. Overall, it held water and was okay. But it wasn’t what I’ve been looking for. I was searching for more inspiration”, going on to hint that he didn’t quite see eye to eye with the creative team.
Asked about whether he might return in a sequel he replied: “I don’t know about that. Nobody knows. It wasn’t talked about, except in the press”.
