1. First footage from Iron Man shown (2007)
This is number one for me because it was mine and the rest of the world’s introduction to the MCU. There had been no footage released of Iron Man to the public to that point, so no one really knew what to expect. The second I saw the leaked footage online that summer in 2007, I knew It would be special for years to come. I will always remember seeing the final moments of the footage where Stark, in his Mark III suit, breaks the sound bearer. It really made my heart go flying.
