Metallica and demo-bats make for a killer combination.

Warning: This article contains spoilers fromStranger Thingsseason 4, Volume 2.

Still, the 29-year-old British actor is more of a glass half-full guy.

“To be part of it in any capacity is still pretty great,” Quinn says.

The Hawkins crew devised a plan to destroyVecna/Henry/One(Jamie Campbell Bower).

Meanwhile, the others snuck into the Upside Down to attack Vecna’s defenseless body.

ENTERTAINMENT WEEKLY: Did you know going into this that your stint onStranger Thingswas finite?

JOSEPH QUINN:I didn’t know for certain.

I wasn’t optioned for another season, so I had a suspicion that they had something planned.

We did see Dacre Montgomery come back, even though Billy got killed off in season 3.

There might be a little something.

You wanna be as informed as you’re able to be when you are in your performance.

Are there any specific emotional beats that stick out in your mind?

I think the relationship with Gaten.

It’s kind of awful dissecting your own work.

The reason you’re pressing certain buttons you just find with your intuition.

Are you sad to be hanging up your ’80s wig ?

I became pretty fond of it by the end, just ‘cause it is a silly thing.

But I won’t miss it.

It itched, so I won’t miss that.

Your big moment at the end where Eddie is getting swarmed by all these demo-bats.

What do you remember from actually filming it?

They were difficult to work with.

They weren’t there, so that was quite funny.

I remember thinking that you don’t get to do this all the time in this life.

So I felt very lucky.

It was a series of night shoots.

I remember it being very thrilling.

We were very pressed for time, so I remember being pretty adrenalized and quite caffeinated.

So you filmed this on location.

It wasn’t on a sound stage.

No, no, no, no.

All of that stuff was in the trailer park, which was great fun.

It’s way better to be outside with that stuff.

Were there tennis balls for reference for all these demo-bats?

There were bits with contact with the shield and stuff.

There would be someone with a stick and a tennis ball hitting me, which felt funny.

It was good fun.

I think that the Duffers have played a blinder with this one.

Also, having Max’s brush with death straight after, it’s a real double jab.

It felt very poignant that Eddie takes his last breath in the arms of Dustin.

What was it like working with Gaten on that final scene with Eddie?

Then later on, because we didn’t have time to do Gaten’s coverage, we went back.

So we shot Gaten’s stuff, I think, months later.

It felt quite weird having that length of time between turning around.

But I think we were both very glad to get that monkey off our back.

Working with Gaten has been such a joyous experience.

He’s a brilliant person and a wonderful actor.

I was spoiled to have the amount of stuff that I got to do with him.

Music has been such a big part ofStranger Thingsin general but this season specifically.

You have this really killer guitar moment.

Were you a big fan of Metallica coming into this?

The Black Albumwas an album that I loved growing up, but I wasn’t a huge metalhead.

It’s been an interesting foray.

It’s one of those weird life things, isn’t it?

Does this song work?

And this came out so soon.

It was the perfect song for it.

You play guitar too, right?

I’ve played since I was young, but I don’t play every day.

But Icanplay, yeah.

Did you record any of the guitar riffs yourself for the “Master of Puppets” moment?

Nothing that you hear, but I was playing it on the day.

We had a backing track and I was playing along with it.

It’s a pretty adolescent fantasy to be a rockstar, isn’t it?

I felt like one for a night.

It was great having Gaten up there with me.

They really turned it up when they played “Master of Puppets” and the whole crew were there.

So it felt like a real celebration.

You have a film coming up calledHoard.

What can you tell me about that project?

It’s an independent film set in Southeast London.

She’s got something about her.

I’ve got a good feeling about it, I say cautiously.
