Tom Hiddleston Reveals the One MCU Project You Must Watch Before ‘Avengers: Doomsday’

Marvel Studios is preparing for one of its biggest releases yet with Avengers: Doomsday, the next major crossover event in the Marvel Cinematic Universe. The film brings together an enormous cast of heroes from across the MCU, including the Avengers, the Fantastic Four, the X-Men, and several fan-favorite characters from Disney+ series.

It is also set to mark the return of Robert Downey Jr., this time playing Doctor Doom instead of Iron Man, making it one of the franchise’s most anticipated movies in years.

With the movie arriving in theaters on December 18, many fans are wondering which Marvel projects they should revisit beforehand. Because the MCU has expanded across both movies and streaming shows, it can be difficult to know which stories will have the biggest impact on Doomsday. One of the biggest questions has centered on Loki, especially after the character’s major journey in his Disney+ series.

Tom Hiddleston recently shared his thoughts on the topic during an interview with TechRadar while promoting his new National Geographic special, Pompeii: Out of Time. The actor was asked whether Marvel fans should watch Loki before heading into Avengers: Doomsday.

Hiddleston has played Loki since 2011’s Thor and has become one of the MCU’s most beloved characters. Although he avoided revealing any details about Doomsday’s story, he did encourage fans to spend time with the Disney+ series.

“I will always say that people need to watch it,” Hiddleston told TechRadar when asked about Loki. While he stopped short of saying the show is absolutely required viewing before Doomsday, his response strongly suggests it will help fans better understand where the character is when the new movie begins.

The actor has become well known for carefully avoiding Marvel spoilers, and this interview was no different. He did not reveal how large Loki’s role will be or explain how the events of the Disney+ series connect to the upcoming film. However, many fans believe the ending of Loki Season 2 could be one of the most important pieces of the puzzle heading into Marvel’s next crossover event.

Loki’s solo series explored the Time Variance Authority, alternate timelines, and the growing threat of the multiverse. By the end of the show’s second season, Loki’s story reached a dramatic conclusion that completely changed his place within the MCU. Because Avengers: Doomsday is expected to focus heavily on the multiverse and Doctor Doom, many viewers have long assumed that Loki will play a significant role.

Marvel has already confirmed Hiddleston’s return through the film’s official cast announcement, and fans also spotted him briefly in the movie’s first trailer. Although his appearance only lasts a moment, it was enough to spark countless theories online about how Loki fits into the larger story.

Hiddleston’s comments have only added to that speculation. While he refused to answer questions about reunions with Thor or reveal what Loki will actually be doing in the movie, his recommendation to watch the Disney+ series has convinced many fans that its events will matter.

Hiddleston was intentionally careful with his answers but appeared to hint that Loki provides important context for his character before Avengers: Doomsday begins. That makes sense considering how much the series expanded the MCU’s understanding of timelines, variants, and the multiverse itself.

For fans planning a Marvel marathon before December, Loki now seems like one of the safest choices to include. Whether it ends up being essential viewing or simply offers valuable background, Hiddleston clearly believes the series deserves attention before audiences return to see the God of Mischief on the big screen in Avengers: Doomsday.
