The Bruce Master

This is the Master who appeared in the ill-fated "TV Movie" that introduced the Eighth Doctor. As the film was set in America, the Master steals the body of an American EMT named Bruce, played by American actor Eric Roberts (brother of Julia Roberts). Since the Master apparently dies in the movie, one would think that would be the end of him, but Big Finish transcends all boundaries, and convinced Roberts to return to the role in 2019.
