Chapter 466: Chapter 383 Meeting with Harvey

In the original Captain America comics, Cap became a Super Soldier after the serum injection.

But the idea of injection associated with drug use could lead to some negative social impacts, so in this movie, Cap needs to undergo some physical training first, then through oral medication, serum injection, and exposure to Vita Rays to stimulate muscle growth and complete the transformation.

In the script, the exposure to Vita Rays is described as an extremely painful process; the stronger the ray energy, the more intense the pain, which ordinary people simply cannot bear, so during filming, Link needs to let out a series of agonizing roars.

"Turn it off! Turn it off!"

In the laboratory on the set, Agent Carter heard Steve shouting in pain inside the experiment pod.

"Turn it back, Mr. Stark, turn it back, turn it off!"

Dr. Erskine shouted.

Howard Stark, the father of Iron Man, held the control valve, ready to reduce the intensity of the Vita Rays.
