Last year, Idris Elba mentioned that he and Tom Hiddleston would reprise their roles as Heimdall and Loki in "Avengers: Age of Ultron." While Heimdall did put in an appearance, however, Loki was nowhere to be seen, and director Joss Whedon revealed to MTV News why the fan favorite trickster was cut from the final product.

"We did shoot something, but it didn't play," he explained. "The movie has so much. It's so filled. We didn't want it to feel overstuffed. I really wanted to have Loki in it, but I understood the decision that there were now too many voices in the chorus."

"At some point the embarrassment of riches is actually embarrassing," he shared a laugh.

"Avengers: Age of Ultron" is currently in theaters.
