Live from the premiere of "The QuaxsFall Guy," it's an "SNL"-themed stunt.

Ryan Gosling and Mikey Day attended the Los Angeles premiere of "The Fall Guy" on Tuesday dressed as their characters from April's viral "Beavis and Butt-Head" sketch on "Saturday Night Live." The actors posed for photos on the red carpet in full makeup and costume and even participated in an interview in character, according to a clip shared on social media.

But Gosling wasn't in costume for the entire premiere, as he also posed for photos on the red carpet wearing a green suit. He stars as a stuntman in "The Fall Guy" opposite Emily Blunt, who plays a film director.

In the sketch from the Gosling-hosted April 13 "SNL" episode, the "Barbie" star and Day played two people sitting in the audience of a town hall who look suspiciously like Beavis and Butt-Head, but both insist the resemblance is coincidental and they are simply there to hear a discussion about artificial intelligence.

The sketch was a big viral hit, in part because nearly every participant ended up breaking character. Heidi Gardner, who played the town hall moderator, laughed particularly hard after turning around to see Day in his Butt-head costume, leading the studio audience to erupt in applause.

Gardner later spoke with Vulture about what led her to crack up so much. Contrary to speculation, she confirmed it wasn't because the live show was her first time seeing the actors in costume.

"When I looked and saw Mikey in the dress rehearsal, I lost it," she told the outlet. "I was shocked. I'm thinking about it right now and laughing. I recovered and tried to tell myself in between dress and the live show, 'You can't laugh like that again.' I was trying to imagine seeing him in my head so I was prepared for it, but I just couldn't prepare for what I saw. I really tried."

It was an especially giggly episode of "SNL" in general, with Gosling and cast members breaking into laughter in virtually every sketch. Speaking to USA TODAY on the red carpet of the Writers Guild Awards last month, "SNL" star Bowen Yang said Gosling set the tone.

"The host always shapes the sensibility of the show, and as we've seen, he is ultimately a very goofy man," Yang said. "He is just easily amused, and that makes it fun for the rest of us."

Yang added that it was "really hard" to stay in character amid the "contagious" laughter throughout the episode.

During his "SNL" monologue, Gosling was joined by Blunt, who helped him promote "The Fall Guy" with a parody of Taylor Swift's "All Too Well" about their films "Barbie" and "Oppenheimer." Swift later expressed approval of the spoof, writing on Instagram, "Watch me accidentally catch myself singing this version on tour. This monologue is everything."
