After Marvel Studios shocked MCU fans with a Captain America 4 confirmation at San Diego Comic-Con 2022, but the studio took it a step further by announcing Tim Blake Nelson's comeback as Dr. Samuel Sterns at the D23 Fan Expo.
This will be the second MCU project for Nelson after portraying Sterns in 2008's The Incredible Hulk, which also brings back other big names from that very film like Liv Tyler's Betty Ross as Phase 1 ties are brought back into the fold.
And with this movie being Sam Wilson's first full adventure wielding the Captain America shield, he'll have his hands full with an antagonist, unlike anything he's seen before.
Captain America 4 Villain Arrives on Set
Fans saw the first look at Tim Blake Nelson on the set of Captain America: New World Order as he reprises his role as Dr. Samuel Sterns, who will eventually become the villainous Leader in what will reportedly be a "very comic accurate" adaptation.
Nelson is seen walking next to a row of trailers dressed in a green collared shirt and purple pants, tying back to the classic colors of the leading character from his original MCU movie, the Hulk.
His hands also appear to be painted green, which could be the first step in his makeup process that will make him look like the Leader in this sequel.
Nelson also dons a scraggly but short beard in these images along with messy hair, teasing his dark path to villainy.
Leader Actor Ready for MCU Comeback in Captain America 4
While plot details for Captain America 4 remain under wraps, having Tim Blake Nelson back after 15 years is already bringing a great deal of excitement for fans.
After all, his character has been one of the longest-hanging plot threads in MCU history after Samuel Sterns was accidentally injected with the Hulk's blood and transformed into the Leader.
These set photos are the start for Nelson in his return as he finally gets to embrace the superpowered version of his classic Hulk antagonist, which was teased for a moment when the Hulk's blood made his head start to expand.
Captain America: New World Order is currently filming and will debut in theaters on May 3, 2024.
