In his pursuit to take over Hydra, Grant Ward has sought out the estranged son of former leader Baron Wolfgang von Strucker to help him rebuild the nefarious organization. Werner von Strucker has been living a life of luxury while being kept out of the family business, but he's ready to prove his worth.

Spencer Treat Clark joins "Agents of S.H.I.E.L.D." as the young Strucker, who has been living under the pseudonym Alexander Braun and enjoying his father's wealth surrounded by beautiful women on large yachts.

The 28-year-old actor is best known for his early roles in films such as "Gladiator," "Unbreakable" and "Mystic River." He has also appeared on TV shows such as "Mad Men," "Law & Order: Special Victims" and "The Good Wife."

1. Clark was already a big fan of the Marvel Cinematic Universe.

It doesn't get much better than joining a show and a franchise that you already love, and Clark hit the jackpot on "S.H.I.E.L.D." playing the son of Baron Wolfgang von Strucker who the Avengers killed in "Avengers: Age of Ultron."

"This is his attempt to reconcile the death of his father, sort of prove himself as an individual," the Connecticut native told Marvel. "I want to see where his relationship goes with Ward because right now it's really contentious. I would think that they would come to some sort of arrangement and some sort of agreement but I have no idea."
