Joseph Quinn Improvised One Of Stranger Things Finale’s Best Lines

While the totally tubular Stranger Things script is mostly the creation of its talented team of writers, it turns out that one of the best lines from the finale was actually improvised by Joseph Quinn. 

WARNING: CONTAINS STRANGER THINGS SEASON FOUR SPOILERS 

Quinn, 29, plays guitar-shredding Eddie Munson, the leader of the Hellfire Club at Hawkins High School – until his untimely death, of course. 

Before heroically sacrificing himself in the Upside Down as he succumbed to the bats, we saw Eddie hot-wiring a camper van with Steve (Joe Keery). 

When Robin (Maya Hawke) expressed her concern at the thought of Eddie driving, he assured her that he won’t be the one behind the wheel. 

Looking up at Steve with a smile, he said cheekily: “Harrington’s got it... Don’t ya big boy?” 

Over on Twitter, the show’s writers revealed that the line had come from Quinn, having recently taken to the platform to share some of the finale’s best improvised moments. 

One fan had asked: “Did he improvise the ‘don’t you, big boy?’ at Steve in the camper van too? just asking for a friend.” 

The writers simply replied: “Yes.” 

Quinn also improvised his character’s final line, having told Dustin: “I think it’s my year, Henderson. I think it’s finally my year. I love you man.” 

As Eddie died in his arms, Dustin replied: “I love you too.” 

The writers explained: "'I love you, man' was improvised by Joe." 

Along with 'Erica, help', which was improvised by Caleb, another moment that wasn't originally in the script was that passionate kiss between Hopper and Joyce.

That, according to the writers, was something that David Harbour and Winona Ryder added on the day of filming - prompting one Twitter user to joke in the comments: "Starting to sound like all the best stuff wasn’t scripted… what were y’all getting paid to do?"

Quinn recently admitted he had 'no idea' his character was going to die, saying it's 'a shame' not to be able to return.

Speaking to Variety, he said: "I knew that I wasn't optioned. I had a feeling that we would finish his arc this season. I couldn't have imagined the manner in which he would leave, but yeah, I think it's a weird thing. It's kind of bittersweet.

"I would love to go back to that set and to see those people again. But sometimes there's a beautiful arc that they've written and he's such an empathetically written role and they're very rare, these kind of roles.

"It feels a little bit like a lottery ticket and I feel incredibly grateful, but it's a shame not to be able to come back. Onwards."
