Ah, the movie that started it all! Did you know that it was Marvel Studios’ first-ever self-financed film? The script hadn’t even been finished when filming began, and most of the dialogue was ad-libbed!

   The Consultant (2011)
2. Captain America: The First Avenger (2011)
   Doctor Strange (2016)

The director of "Doctor Strange," Scott Derrickson, is a huge fan of the character. He wanted to be chosen as director for the film so badly that he even spent his own money on the concept video that he pitched to Marvel!

   Marvel’s Jessica Jones (2015)
2. Marvel’s The Avengers (2012)

To prepare for the role of Peter Parker, Tom Holland attended the Bronx High School of Science for a few days. Holland says that a classmate found him strange and asked him what was going on – when he explained to her that he was a British actor playing Spiderman, she called him “nuts”!

When Paul Rudd was cast as Ant-Man, and he told his son – then nine years old – about it, his son said: “Wow, I can’t wait to see how stupid that’ll be.” We’re not sure if he’s changed his mind about his father's role since then!

   Thor (2011)
2. Marvel’s Agent Carter (2015)
   Marvel’s Iron Fist (2017)

James Spader was the first choice for the role of Ultron because of his “hypnotic” voice. Apparently, his performance was so awe-inspiring that the rest of the cast cheered after his first take!

1. Marvel’s Iron Fist (2017)
   Doctor Strange (2016)
2. Marvel’s Runaways (2017)

1. Marvel’s Luke Cage (2016)
   The Incredible Hulk (2008)
2. Black Panther (2018)
   Marvel’s Inhumans (2017)

   A Funny Thing Happened on the Way to Thor’s Hammer (2011)
2. Marvel’s Agents of S.H.I.E.L.D. (2013)

   Marvel’s Inhumans (2017)

Mark Ruffalo and Tom Holland are notorious for spoiling Marvel films. Because of this, Ruffalo was given a fake script for "Infinity War" and Holland wasn’t even allowed to read the script at all!

There were two other Marvel characters present during World War II who were going to make cameos in the film: Erik Lehnsherr (Magneto) and James Howlett (Wolverine)! Sadly, the cameos never worked out because of issues concerning rights.

1. Ant-Man (2015)
   Marvel’s The Defenders (2017)
2. Guardians of the Galaxy Vol. 2 (2017)
   Doctor Strange (2016)

Director James Gunn created a script specifically for himself and Vin Diesel called the “Groot Version.” It contained all of Groot’s lines in English so that Diesel would be able to get the inflection in “I am Groot” right every time!

1. Thor: The Dark World (2013)
   Team Thor (2016)
2. Marvel’s Daredevil (2015)
   Thor (2011)

2. Marvel’s Iron Fist (2017)
   Thor: The Dark World (2013)

Ant-Man and Wasp are founding members of the Avengers, but director Joss Whedon decided to cut them from the film. He did this both because there were already too many characters in the movie, and because he wanted Ant-Man to be introduced into the Universe with his own solo film!

1. Spider-Man: Homecoming (2017)
   Marvel’s Cloak & Dagger (2018)
2. Team Darryl (2018)
   The Consultant (2011)

2. Captain America: Civil War (2016)
   Team Darryl (2018)

This 2013 short was featured on the Blu-ray of "Iron Man 3" and featured Peggy Carter on a solo mission. The short was so well-received that it led to the creation of a TV series centered on the character!

2. Avengers: Infinity War (2018)

Though both the films and TV series take place in the same continuity, the Stark building is missing in shots of the New York skyline in "The Punisher!" It should be near the Empire State Building.

2. Guardians of the Galaxy (2014)
