Rhys Williams(1897-1969)

He made his film debut in Qu'elle était verte ma vallée (1941), which takes place in rural Wales. The movie was actually filmed in Hollywood with a cast of English, Irish, Scottish and American actors. Originally hired solely to coach the actors in their Welsh accents, Williams, who was the only genuine Welshman on the set, was given the role of the prizefighter by director John Ford.
