What is Mark Williams’ role in Harry Potter?
Arthur Weasley character description
Mark Williams (actor) played Arthur Weasley, the father of the Weasley family, in all seven Harry Potter films from 2001 to 2011.

Mark Williams filmography beyond Harry Potter
Beyond Harry Potter, Mark Williams (actor) appeared in 101 Dalmatians (1996) as Horace, one of Cruella de Vil’s bumbling henchmen.

Mark Williams (snooker) has a Harry Potter-themed nickname — “The Welsh Potting Machine” — that has nothing to do with the actor. Fans frequently confuse the two, asking the snooker player about flying cars and the actor about 147 breaks.
