Marvel has released a new video drawing a line from the beginnings of the Marvel Cinematic Universe to the unstoppable entertainment juggernaut it's become today. Here's the video:

The first film in the MCU was Iron Man, released in May 2008. Speaking before the film opened, director Jon Favreau said "I really don't know how people are gonna react to this thing." But he could soon breathe easy, as a combination of action, humour, cutting-edge effects and a star turn from Robert Downey Jr made Iron Man a huge hit and paved the way for Marvel's other superheroes to leap from page to screen.
