Los Angeles, July 28 (TIWN) Actor Joseph Quinn was held in a "dungeon" by a US immigration official but was finally released when he was recognised as Eddie Munson from the popular show 'Stranger Things'.

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

"One of his colleagues looked over at him, looked at me, and said: 'Leave Eddie alone!' And then (the colleague) said, 'It's Eddie from 'Stranger Things', and he was like, 'You're Eddie Munson?' "

The officials eventually let Joseph go, but not before quizzing him for some spoilers.

He 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."

During his debut appearance on the talk show, Joseph presented Jimmy with a Hellfire Club t-shirt, much to the delight of the talk show host, who said he was "honoured" to receive the gift.

He said, "I am honoured. I'm part of the Hellfire Club? I will wear this. I cannot wait."

Joseph previously admitted he felt like a "sociopath" when trying to perfect an American accent for the show.

He said, "You feel like a sociopath. 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?' "
