About Gabriel Byrne
Gabriel Byrne plays Earl Haraldson in Vikings within a career that includes Tom Reagan in Miller’s Crossing, Dean Keaton in The Usual Suspects and Dr. Paul Weston in In Treatment. His screen work also reaches from King Uther in Excalibur to Steve in Hereditary. That breadth makes the early Kattegat ruler an entry point into a much larger film and television career.
In Treatment is the most rewarding next stop for viewers interested in sustained, conversation-led performance. Miller’s Crossing places him at the centre of a film, while The Usual Suspects is a shorter ensemble choice. Those routes show a performer working with suspicion and private pressure in settings far removed from Haraldson’s hall.
