Thor: The Dark World

Not only did "Thor: The Dark World" get the worst reviews of the franchise, but director Alan Taylor publicly expressed disappointment over it. Taylor said that he felt like he had freedom while shooting the movie, only for the studio to change it in post-production.

Thor's Eyebrows

"Thor: Ragnarok" solidified what the character was all about, but the God of Thunder was on shakier ground at first. Marvel Studios President Kevin Feige has said that they went too far in trying to make Chris Hemsworth resemble the character in the comics, even dying his eyebrows blonde.

Coulson's Return

The death of Agent Phil Coulson in “The Avengers” devastated fans, and many were thrilled to see him alive again in "Agents of SHIELD." However, Joss Whedon, who directed the film and co-created the show, had mixed feelings about it, saying it took “some of the punch out” of Coulson’s death scene.

Drax's Line

James Gunn has talked about how one of his favorite Drax the Destroyer lines in "Guardians of the Galaxy" was omitted from the final cut. Drax made a joke about Earth, saying he would like to “kill many people there,” and Gunn has expressed his desire to “George Lucas" the line back into the movie.

The Incredible Hulk

“The Incredible Hulk” has something of a weird reputation, and director Louis Leterrier has contributed to it by discussing its shortcomings. Leterrier has said that he started directing without a screenplay and that only the first half of the film is really his.

Killing Klaue

“Black Panther” covered some very heavy material, so Ulysses Klaue provided moments of welcome levity. Director Ryan Coogler knew that killing the character was the right move, but it still pained him to do so, as he enjoyed Klaue and actor Andy Serkis so much.

The Ancient One

There were several thorny elements about the “Doctor Strange” comics that needed to be ironed out for the big screen, including the stereotypical portrayal of the Ancient One. Kevin Feige and director Scott Derrickson have said that casting white actress Tilda Swinton was wrong, even though it was an attempt to break stereotypes.
