Now, anyone can watch Downey's audition tape for themselves to see how he landed the iconic role.Uploaded to Fandango's Twitter account, the video begins with Jon Favreau -- who directed the first two Iron Man films and plays Happy Hogan in the Marvel Cinematic Universe -- talking about how Downey was at a point in his career where he was ready to "break out and do something really big and exciting."RELATED: How Much Robert Downey Jr. Was Paid For Each of His MCU FilmsCasting Director Sarah Halley Finn follows up by saying that Favreau was passionate about casting Downey as Iron Man, but she suggested they do screen tests as the actor wasn't, as she puts it, "a slam dunk approval," despite everyone feeling sure about casting him on a creative level.

The video then cuts to footage of Downey getting ready to do the audition, while voiceover from Finn talks about that fateful day. Fans then get to see Downey perfectly saying one of the lines from the film to another actor.

"I wouldn't call it an out of body experience," Downey states as he appears on camera, "but it was one of those rushes that I'm sure, like, somebody would feel if they were about to play a big sporting arena, playing for the ring or something like that. It was just like 'am I gonna pass out, or am I gonna nail this?'"
