The break-out star from season four revealed all that he could about the final two episodes of the season - and also talked all about his glorious '80s wig.
We're all running up that hill in anticipation of how this upcoming season four is going to turn out, and in anticipation of its release this July, new 'Stranger Things' actor Joseph Quinn has dished out a tease of what fans can expect.
The Guardian caught up with the British actor, who previously starred in the likes of The National Theatre production of 'Mosquitoes' with Olivia Colman, with Helen Mirren on the miniseries 'Catherine The Great', and who also made a brief appearance in season seven of 'Game of Thrones'.
Quinn plays the role of wrong-place-at-the-wrong-time teen Eddie Munson in Netflix's fantasy series, the over-enthusiastic leader of Hawkins' Hellfire Club, who loves nothing more than to scare the bejesus out of Dustin (Gaten Matarazzo) and his friends. However, the mulleted character gets dragged into the Upside-Down aspect of Hawkins when he witnesses the brutal murder of cheerleader Chrissy (Grace Van Dien) by Vecna, and becomes the number one suspect in the string of teenage murders around town.
When asked if he can tell viewers anything about the season four finale, he joked: "The thing is, they’ve got my family tied up somewhere and if I spoil anything, I’ll never see them again."
However, Joseph Quinn did tease a 'Stranger Things' ending like no other - featuring a memorable guitar scene? Sure. He continued: "No, I can say there’s a guitar scene and that the scale and ambition are astonishing. All the seeds that have been planted bear fruit and it’s just carnage.
"You know the finale is two-and-a-half hours, right? Ending with this monster, feature-length episode is so bold."
When asked about his beautifully mulleted hair-do for the series, Quinn admitted "99.7% of the work is that wig", adding: "Okay, maybe only 99.6% is the wig. It’s objectively ridiculous. When I take it off, that helps me go unrecognised, so it’s been a blessing in that respect."
Asked how he got himself into his Munson's frame of mind, he added: "I tried grappling with 'Dungeons & Dragons', but accepted that wasn’t going to happen. Music was my main way in. I listened to a lot of heavy metal – Black Sabbath, Metallica, Dio – and I worked with a brilliant vocal coach called Mary Howland."
Could he be returning for the fantasy series' final season? He admitted he'd be "furious" if they didn't bring him back, adding "I'd love to, if they’ll have me".
'Stranger Things' season four will conclude on Netflix on July 1 when the final two episodes of the season will premiere.
