Jeremy Strong was almost a pre-serum Chris Evans in Captain America
The Emmy winner was nearly a body double for The First Avenger in his introduction to the MCU

Before he was the perpetually sad-eyed Kendall Roy in the Emmy-winning HBO series Succession, Jeremy Strong was nearly our Steve Rogers… in all things but face.
A weird entry in the MCU’s long list of casting “what if’s,” Strong revealed that he almost took on the role of Chris Evans’ pre-Super Soldier Serum body in the 2011 superhero origin story Captain America: The First Avenger. In an interview with The Sunday Times, the Armageddon Time actor divulged that when he was “broke” and “needed the money,” he had auditioned to play a less bulked-up version of the hero, with Evan’s face CGI-ed over his own.
“OK, fuck it, I will tell you this story,” said Strong to the outlet, starting his would-be casting tale by setting up that after failing to get a part in 2011's Daniel Craig-led Cowboys & Aliens, he was offered a role in “a top-secret film about Captain America.”
“They needed someone to play Captain America’s young body, before he turns into a superhero,” said the Succession star. “They said they needed a transformational actor and would use CGI to put the actual actor’s face and voice over my own.”
