Petition for Christian Coulson (Actor who plays Tom Riddle in Chamber of Secrets) to return to the Harry Potter Franchise in Fantastic Beasts and where to find them! If Voldermort ever returns to the Fantastic Beasts series, we hope to see Christian acting as Tom Riddle, because he is the best young Tom that we have ever had, and he is the perfect Tom in many potter fans' mind. I assure you age does not matter in many fans' mind (and Christian still looks the same tbh), since he is the best Tom Riddle!
