I can't believe that.
Even if I granted that many actors DID see the role as toxic, there would STILL a line of British actors knocking at the door to play this iconic role.
Its what been said online, no one wants to play the character currently and the show ratings have been in the toilet the last couple of seasons, so why would anyone want to get onboard of a show that is clearly a sinking ship and could well kill their career if they take it on?
