Tom Hiddleston has revealed if you need to watch Loki on Disney+ to understand his character's role in Avengers: Doomsday.

Speaking exclusively to Tech Radar, the fan-favorite actor, who has played Loki in the Marvel Cinematic Universe (MCU) since 2010, said "I will always say that people need to watch" his character's standalone series. However, Hiddleston wouldn't be drawn specifically on whether it was essential to stream the show prior to Doomsday's release on December 18.

Marvel fans who've seen the Hiddleston-fronted program will already know how its second and final season ends. On the off-chance that you haven't watched it yet, I'll refrain from spelling out exactly what happened in this article. For those who need their memory jogged, my spoiler-filled Loki season 2 ending explained piece holds the answers you seek.

One thing that every MCU fanatic will know by now, though, is that Loki will return in Avengers: Doomsday. Indeed, not only was Hiddleston part of the initial 27-strong Doomsday cast announcement in March 2025, but he also made the briefest of appearances in Avengers: Doomsday's first official trailer, which surprisingly made its public debut yesterday (July 20).

Naturally, fans have myriad questions after the release of said trailer, including a couple concerning Loki. How big of a role will he play in the Marvel Phase 6 movie? Will he be reunited with Thor? And, perhaps most important of all, does Loki's Disney+ show have any bearing on the story that Doomsday will tell?

As part of a wider chat I had with Hiddleston for his new National Geographic docudrama Pompeii: Out of Time, which airs on Disney+ and Hulu on July 23, I put those exact questions to him. Predictably, Hiddleston, who has plenty of experience dodging spoiler-based Marvel questions, wasn't forthcoming with definitive answers.

Nonetheless, he did appear to drop a tiny hint that anyone who wants to comprehend Loki's role in Avengers 5 should seek out the character's solo show on Disney+, aka one of the world's best streaming services.

"I always say that people need to watch Loki," he told me with a wry smile. "I'm really proud of that show — I poured my whole soul into it and I love playing Loki. It's been 16 years now and, you know, I got to the end of Avengers: Infinity War, and that seemed to be the end of the Odinson saga.

"But, then Loki, as a series, was about placing Loki in the new context [by] taking him out of time and his reality," Hiddleston continued. "He's confronted with his compulsive, self-destructive, repetitive patterns of behavior, and gives him this capacity to be an agent of his own destiny. It was such an enjoyable experience because the whole show is about identity, purpose, and belonging, and also about time and how we perceive it and how best to use it.

"So, yeah, I would always say, if you haven't watched it, go and do so," he added. "And, if you haven't watched it before Doomsday, go and watch it again."
