Columbus explained that Williams lost out on the role because casting him would have broken a rule to avoid casting any American actors in an effort to “maintain a degree of authenticity,” perTotal Film.

“I had a conversation with Robin Williams, who wanted to play Lupin,” Columbus, who is American, recalled. “It was very difficult for me to say, ‘It’s all British. There’s nothing I can do.’ "

Columbus directed both the first and second Harry Potter films, while Alfonso Cuarón stepped in for the third, which featured Thewlis' first appearance as Lupin in 2004. The actor went on to play the role up until his final appearance in 2011.

Casting director Janet Hirshenson mentioned the British actors rule in a 2016 interview withHuffPost, telling the outlet a similar story about Williams' hopes to join the franchise. She said he had been turned down for the role of Hagrid, which later went to Robbie Coltrane.

“Robin [Williams] had called [Chris Columbus] because he really wanted to be in the movie, but it was a British-only edict, and once he said no to Robin, he wasn’t going to say yes to anybody else, that’s for sure,” she said at the time. “It couldn’t be.”

Williams, who died in August 2014, briefly mentioned theHarry Pottercasting rule in a 2001 interview withThe New York Post.

“There were a couple of parts I would have wanted to play, but there was a ban on [using] American actors,” he said, perTheIndependent, before adding, “Maybe one day. Say if [Harry] goes to Yale and becomes president.”
