Isaacs thanked his Harry Potter co-star for the years of laughter and friendship, while also joking about Felton’s beard.
Jason Isaacs and Tom Felton’s birthday correspondence occurred over on their personal Twitter accounts.
Plus, he let Felton know that he’s now as old as Jesus, which is a hilariously bizarre way of celebrating his on screen son’s birthday.
While the younger actor no doubt got plenty of well wishes from his friends, the message from Jason Isaacs is one that quickly went viral for fans of the Wizarding World.
