For interested parties, Reddit also has a chronological viewing order chart that lists the full timeline from The First Avenger to Iron Fist.
According to a post on the Marvel Studios Reddit, a viewer would have to spend 6 days, 15 hours, and 41 minutes to watch the whole franchise.
Since its inception with the premiere of the original Iron Man film in 2008, the Marvel Cinematic Universe has become one of the most successful franchises in Hollywood history.
As one would expect, this is hardly something one can do overnight.
