Son of Alun Armstrong.

Played an on-screen son to his father Alun Armstrong in The Hollow Crown. Joe played Hotspur to his father's Northumberland.

Attended Elliot School and completed his higher studies at The University of Bristol.

Has two brothers, Dan, who was in the band The Rushes, and Tom, who is a travel writer.

While the good-looking Joe appears completely different from his rugged father Alun, he looks extraordinarily like him when seen in profile.
