In an recent interview, Bill Nighy discusses in detail his role in the seventh film in the Harry Potter franchise.
When discussing his film character, Rufus Scrimgeour, he states: "Scrimgeour is a tragic figure. He knows what's coming.
"It's a very moving thing to play." He also states:
"he has an interesting relationship with Harry, who views him initially with contempt. But then it's softened by subsequent events."
Given how little (yet important) a role this character had in
"Harry Potter and the Deathly Hallows", it is surprising, yet relieving, that WB has decided that Bill Nighy's character makes the cut.
