The new Thor: The Dark World DVD and BluRay releases have bonus commentary where Alan Taylor talks with Kevin Feige, cinematographer Kramer Morgenthau, & Loki himself Tom Hiddleston.
Film School Rejects compiled a list of 22 things learned from the commentary. You can check out a few of the highlights below and the entire list at this link.
-Originally, the film did not have a prologue. After test audiences wanted to know more about Malekith (Christopher Eccleston), a prologue was created during post-production, featuring mostly CGI action and only a few practical shots of the key actors in close-up.
-The stone giant that Thor (Chris Hemsworth) faces off against at the battle of Vanaheim is Korg, also known as the Stone Man from Saturn. Although this version looks a bit different, this is the first enemy that Thor fought in his first comic issue.
-Loki (Tom Hiddleston) tossing the cup in the air and catching it while lying on his prison bunk was a nod to Steve McQueen tossing a baseball in solitary in The Great Escape.
-Before shooting the scene in which Loki shape-shifts into Captain America, Tom Hiddleston put on the Captain America outfit and did his own over-the-top impression of Chris Evans. When it came time to shoot, Evans imitated Hiddleston’s impression of himself.
-Feige admits that he puts the tags at the end of the Marvel movies partially because he wants people to stick around and acknowledge the people who worked on the film. He was inspired by this when he saw Ferris Bueller’s Day Off , which caused him to watch the end of all credits for movies he saw when he was younger.
