One of the best jokes in 'Thor: Love and Thunder' was originally cut from 'Ragnarok,' so Taika Waititi made it '5 times bigger'

• Taika Waititi told Insider that one of the movie's best jokes was originally in "Thor: Ragnarok."

There's one joke in "Thor: Love and Thunder" that has been on writer-director Taika Waititi's mind for years.

In the middle of the movie when Thor (Chris Hemsworth), Jane (Natalie Portman), Valkyrie (Tessa Thompson), and Korg (Waititi) travel to Omnipotence City to seek out the help of the gods against Gorr (Christian Bale), Thor finds himself in a bind when he's singled out by the biggest god of them all, Zeus (Russell Crowe).

Asked by Zeus to stand in front of him, Thor does so but is wearing a cloak to disguise himself. So Zeus uses his powers to easily flick it away, however, he flicked too hard and all of Thor's clothes come off. A shot from behind reveals that Thor has a giant back tattoo that says "RIP Loki," his brother who died at the hands of Thanos in "Avengers: Infinity War."

Waititi revealed to Insider that the Loki tattoo was a joke he wanted to work into the previous Marvel movie he directed, "Thor: Ragnarok."

"That was supposed to be in 'Ragnarok,'" he said. "When Loki faked his death and he's reunited with Thor and Thor can't believe he's alive, he was to say, 'I mourned you, look I even got this stupid tattoo,' and Thor lifts his sleeve and it's a tattoo that says 'RIP Loki.'"

"For some reason it didn't make it into the film, but I was determined to get it into this one so I doubled down and put it on his back," Waititi added.

The joke is amplified because of the size of the tattoo. Waititi said he couldn't take credit for that. It was Marvel Studios head Kevin Feige who came up with that idea.

"Then Kevin was like, 'Can we make it five times bigger?'" Waititi said with a laugh. "So that's why it covered his entire back."

This along with the Taylor Swift-inspired screaming goats who accompany Thor and his team on his latest adventure are two of the major comedy bits in the movie.

"Thor: Love and Thunder" is currently playing in theaters.
