It’s hard to imagine a time when there wasn’t at least one MCU movie in theaters, but back in 2008, Marvel was primarily known as a comics company that had to partner with studios to produce films. Then Iron Man happened, and everything changed.

Marvel Studios and studio president Kevin Feige was determined to pick the best talent over marquee names. “It was liberating to make decisions like that, that I don’t know would have been made at other studios at the time,” Feige told Rotten Tomatoes when he sat down to talk about 10 years of the MCU. That decision paid off — Iron Man was a smash hit – beloved by critics (94% on the Tomatometer) and audiences alike (the film has an Audience Score of 91%).

The Mark II armor was designed and created by Tony Stark after his return from Afghanistan. It features much of the articulation and sleek-design which would appear in the final, Mark 3 armor. While testing the flight mechanism, he noted that ‘icing’ would become a major problem with the Mark II when upper altitudes were reached. It was hinted that Rhodey would be using the Mark II armor in the sequel.

Contrary to the electronically “dumb” Mark I, the Mark II featured a highly advanced compact computer system with extensive sensor systems linked to holographic heads-up display in the helmet, Stark’s personal A.I. system J.A.R.V.I.S being able to interface with it and provide verbal warnings and system status updates.

The outer surface of the armor was high gloss silver. The majority of the panels on the suit were articulated to serve as control surfaces in flight, but main flight stabilization cames from repulsors installed on the palms each hand.

J.A.R.V.I.S.: “Test complete. Preparing to power down and begin diagnostics…”
Tony Stark: “Uh, yeah, tell you what. Do a weather and ATC check, start listening in on ground control.”
