Based on Robert Jordan’s beloved high fantasy book series, Amazon Prime Video’s The Wheel of Time is changing things up in season 3, with Mat’s story taking a sharp U-turn from canon. Played by British actor Barney Harris in season 1 and Irish actor Dónal Finn in season 2, Mat Cauthon continues to be a crucial main character in The Wheel of Time season 3. However, this isn’t necessarily working out as book readers and diehard fans had expected, with the show continuing to take liberties with the book story.
