How Chris Evans Became Skinny Steve In Captain America: The First Avenger

Here's how Marvel Studios transformed Chris Evans into skinny Steve Rogers for Captain America: The First Avenger. Playing a hero in the Marvel Cinematic Universe requires actors to be in great physical shape, and Evans was up to the challenge of looking and moving like a superhero throughout his tenure as Captain America. Audiences first saw Evans' superhero transformation in 2011's Captain America: The First Avenger. While it's more than fair to give Evans credit for his compelling portrayal of the beloved Avenger, Captain America's skinny body double was just as important for taking Cap's story from Marvel Comics to the screen. Indeed, Captain America's skinny-to-buff transformation was crucial in showing the full effects of the Super Soldier Serum, completing Steve Rogers' journey towards becoming the MCU's first super soldier.

For the first act of Captain America: The First Avenger, audiences saw Steve Rogers as he was before becoming one of the world’s greatest heroes. Growing up in Brooklyn, Steve was short and skinny compared to most other men similar in age. According to the Captain America exhibit in the MCU, Steve was only 5'4 and weighed 95 pounds pre-serum. Despite his small frame, skinny Steve Rogers still had the heart and morals that would later make him the obvious choice to become Captain America. Once Dr. Abraham Erskine's (Stanley Tucci) Super Soldier Serum was running through his veins, Steve was suddenly 6'2 and 240 pounds of pure muscle and showcased Evans' true physique. But, thanks to the magic of moviemaking and planning on Marvel’s part, Evans played skinny Steve Rogers too.
