It turns out that Tom Hiddleston (Loki) never intended to pull a trick on death in Thor: The Dark World (2013) and was actually saved by a revamped script based on feedback.
The second standalone installment for the thunder god, often considered to be one of the weaker attempts in the Marvel Cinematic Universe (MCU) for various reasons, forced Thor and Loki to work together against a common enemy — Malekith, ruler of the Dark Elves of Svartalfheim.
The mission to safeguard the Aether led the trickster to sacrifice himself for the greater good, or so it seemed. When a mournful Thor returned to Asgard after containing the threat, Loki was revealed to be actually alive and impersonating Odin on the throne.
Speaking with Empire in a recent interview, Hiddleston revealed that his character was originally supposed to receive a permanent death in Thor: The Dark World. The script had to be changed because the select audience from early test screenings refused to believe that Loki could die this easily.
“It was part of the original pitch and in test screenings, the audience didn’t accept it,” said Hiddleston. “They said, you know ‘He’s obviously coming back. That didn’t really happen.’ And there was a very strange and almost unanimous resistance to it. They decided that wasn’t the end.”
It would be fair to say that everything worked out well for everyone involved. Despite his trickery and shenanigans, Loki remains as one of the most loved fan-favorite characters from the MCU. He made a few appearances after his re-written mortality, playing a major role in Thor: Ragnarok (2017) and a rather shocking scene in Avengers: Infinity War (2018) that would be a spoiler for those yet to watch the movie.
