9) Tom Felton as a New Regular
A couple of months ago it was announced that Harry Potter alum Tom Felton would be joining The Flash season 3 as a new regular character.
Not a lot is known about Felton’s role right now but we do know that he is playing Julian Dorn, a rival forensics expert who is suspicious of Barry and believes there is more to him beneath his “nice guy routine.”
Given his most famous role of Draco Malfoy, many are expecting Felton to take on a villainous identity on the show. When asked about that, the actor teased: “they came to me for a reason.”
