The Wheel of Time boss promises a "seamless" transition with a new actor taking over the key Mat Cauthon role

Deadline

Showrunner Rafe Judkins says of Dónal Finn replacing Barney Harris as Cauthon in Season 2: “It’s always hard but we’re really lucky that Barney is so great in the first season; I love him in the show. And Dónal Finn, who is playing Mat in Season 2, is amazing. I have seen him up on set doing his scenes now and they’re incredible and they fully capture the character. I think it’s a testament to this character and how great the character of Mat is that it really feels seamless between the two actors.”
