This footage was made 10 years ago by Deadpool director Tim Miller but ended up being canned by Marvel because they couldn’t get it on TV. However, this is what paved the way to the development of the first Iron Man movie. Since Iron Man was not widely known a decade ago, the short film had three objectives:

1- Clearly demonstrate that there was a man inside the armor.

2- Show off his wide range of cool powers.

3- Position him clearly as a hero on the same level as Spidey and Hulk by having those characters show how cool they perceive him to be and valued him as a peer.
