Born in Lambeth in 1979, Arthur was born to Irish parents and raised in Battersea, London until the age of 5. He then moved to the town of Bedford where he still resides today. His first experience in front of the camera came in 2008 after being invited to appear in the music video "No More Eatin'" by British artist Plan B. Whilst still working a 'day job' in accounts, Arthur has taken his first steps into the world of television and movies in 2014 and has already worked alongside the likes of Jeremy Irons, Martin Clunes, Chris Hemsworth and David Beckham.
