Fan Casting Banshee in X-Men

Sean Cassidy (aka Banshee) is a free soul who gets irate only when he thinks about his villainous cousin Black Tom, or when someone close to him is threatened. He is a hopeless ladies’ man who has carried a torch for Moira MacTaggart for years. He has a fondness for American westerns. I went with an Irish actor, Domhnall Gleeson. Who is known for the role as Bill Weasley from Harry Potter. Similar to his performance, he's laid back and easy going, and described as "cool". So Domhnall Gleeson... as Banshee.
