One of the crucial landmarks for any actor playing the Last Son of Krypton is the first time they put on that iconic suit. And while Zack Snyder and Christopher Nolan have redesigned Superman's duds somewhat for Man of Steel, it was still a big deal for Henry Cavill.
While doing press for the upcoming Immortals, Cavill revealed the warm fuzzies he got when he first encountered "the suit":
"I got to see it through various prototypes and stages of development. ... But still, the first time I had it all on with the cape, I deliberately didn't look in the mirror as it was going on. I wanted to have that sort of turnaround moment. Probably one of the best moments of my life, to turn around and realize that I'm Superman. There's no other feeling like it. That still hasn't gone, either. Still, when I'm in the trailer, I'm going, 'this is so cool!'"Welcome to the club, kid. LINK
