Comic book writer Stan Lee feels the concept of the twist in Captain America's character is "crazy," but "a good idea."
Speaking at a panel about the plot-line, the 93-year-old comic book writer said, "I don't know that I would ever have thought of it for him to be a double agent, but it's going to make you curious, it's going to make you want to read the books, they'll probably do a movie based on it," reports the Independent.
In a recent turn of events, it has transpired that all this time, Captain America was actually part of a Nazi cult called Hydra, led by The Red Skull.
It is not just fans who have expressed their outrage towards the twist; Captain America actor Chris Evans expressed his shock on Twitter.
Meanwhile, writer Nick Spencer has confirmed that the twist is no gimmick, stating the moment will have "lasting repercussions.
