Joseph is best known for his portrayal of William Shakespeare in the award-winning film Shakespeare in Love back in 1998. Nowadays he’s starring in the creepy American Horror Story. But while we may already know he’s Ralph Fiennes’s younger sibling (not that surprising, given those dashing looks!), Joseph actually has a twin brother too, named Jacob. Jacob prefers to shy away from bright lights of showbiz, working as a conservationist.
