Devon Murray played the explosion-prone Seamus Finnigan, a Gryffindor known for accidentally setting things on fire. Interestingly, Murray was almost cast in Gangs of New York before landing the Harry Potter role—a lucky twist that changed his career path.

While he took on a few smaller roles during the franchise, Murray stepped away from acting after the series ended. He remains connected with fans through social media, sharing glimpses of his life beyond the wizarding world.
