'Stranger Things' star Joseph Quinn says he was held by US immigration in 'a dungeon' and nearly missed 'Tonight Show' appearance

• "Stranger Things" star Joseph Quinn said he nearly missed his appearance on "The Tonight Show."
• Quinn told Jimmy Fallon that he was held in "a dungeon" while going through US immigration.

"Stranger Things" star Joseph Quinn said that he nearly missed his appearance on "The Tonight Show Starring Jimmy Fallon" Monday night because he was held by US immigration.

The British actor made his US late-night talk show debut Monday following his breakout role in the latest season of the hit Netflix series. Quinn played Eddie Munson, the leader of a "Dungeons & Dragons" club who helps the gang save Hawkins from the villain Vecna.

During the interview, Quinn said he was "held up" by US immigration on his way to the show.

"I very nearly didn't make it," Quinn said. "I was taken into, I guess what you could call it more of a dungeon. And I was asked to wait there for about 20 minutes and then I was summoned to this desk where someone asked me, 'What are you doing in the United States, sir?'"

Quinn continued: "I said, 'I'm actually here to meet Jimmy Fallon on "The Tonight Show."' And he didn't believe me."

The 28-year-old actor said that he was only allowed through after being recognized for his role in "Stranger Things."

"And one of his colleagues looked over at him, looked at me, and said: 'Leave Eddie alone!'" Quinn recalled. "And then [the colleague] said, 'It's Eddie from "Stranger Things,"' and he was like, 'You're Eddie Munson?'"

Quinn continued: "[The man asked] 'Do you come back next season?' I was like, 'I don't know,' and he said, 'You better,' and gave me my passport."

The "Stranger Things" actor recently admitted on an episode of the "Off Menu" podcast with comedians Ed Gamble and James Acaster that he felt like a "sociopath" putting on an American accent for the show and had to ask his costar Joe Keery for help.

"After a while I was so far down the rabbit hole, at points I'd be like, 'Do I sound good? Do you like this? Do you like what I'm doing?'" Quinn said. "I was talking to Joe Keery and at one point I was so deep in it, and he was like, 'Dude, I can't save you, but I promise you it's gonna be fine.'"

"Stranger Things" is available on Netflix.
