For more than 15 years, Tom Hiddleston has defined one of the Marvel Cinematic Universe’s most beloved and complex characters. His version of Loki—equal parts menace, humor, and vulnerability—has become iconic. But according to the actor himself, that performance might never have happened without a legendary villain from an entirely different comic-book universe.
In a recent appearance on the Happy Sad Confused podcast, Hiddleston revealed that his inspiration for Loki did not come primarily from Marvel lore, but from The Joker, as portrayed by Jack Nicholson in Tim Burton’s Batman. The impact, he said, was profound and lasting.
“Truthfully, I don’t think I would’ve played Loki without that film,” Hiddleston explained. Seeing Nicholson’s Joker at a formative age reshaped his understanding of what a cinematic villain could be. Rather than a one-note antagonist, the Joker radiated charisma, creativity, and an almost infectious sense of joy. “I understood he was the villain, but he was having such a good time,” Hiddleston said, noting how freeing and inventive that performance felt.
That sense of enjoyment, he admitted, directly informed his approach when he first stepped into Loki’s boots for Marvel. When Hiddleston debuted as the character in Thor, he consciously carried Nicholson’s influence with him, blending mischief with theatricality and emotional depth. The result was a villain audiences loved to watch—even when they disagreed with his actions.
This admiration for classic antagonists is nothing new for Hiddleston. In a 2013 interview, he spoke openly about the performers who shaped his tastes as a young film fan. Alongside Nicholson, he praised Alan Rickman for his delightfully sinister turn in Die Hard, as well as James Mason in North by Northwest. What united these performances, Hiddleston noted, was a sense that the villains genuinely enjoyed themselves.
During the making of Thor, that philosophy became part of the creative process. Working with director Kenneth Branagh, Hiddleston experimented with multiple styles and influences to unlock Loki’s complexity. Some takes leaned toward the grandeur of Peter O’Toole, others toward the restraint of Clint Eastwood—and one version openly embraced the Jack Nicholson approach, where Loki was “having the most fun in the room.”
The revelation highlights a fascinating creative crossover: one of Marvel’s most enduring characters owes a debt to DC’s most infamous clown prince of crime. For fans, it also helps explain why Loki has always felt different from typical villains. Like Nicholson’s Joker, he isn’t just threatening—he’s magnetic, unpredictable, and clearly enjoying the chaos he creates.
