Adam Scott 'makes mistake' as he turns up in character with Severance cast at New York tube station

The cast of Apple TV+ drama Severance showed up at New York's Grand Central station for a pop-up live performance, but things went slightly wrong for one unfortunate star.

The show centres around people working at the fictional company Lumon Industries as they go through 'severance', where their home lives and work lives are kept apart by completely separating their memories.

When in work they can't remember anything about their life outside, and when it's time to clock off they don't remember what they do for a living, which protects company secrets.

Now you know what Severance is all about, you might be interested in watching it, or if you've already seen it then perhaps you'd like to tell your friends about this critically acclaimed show on a streaming platform they probably don't have.

Heading out to Grand Central to drum up some publicity for the show's upcoming second season, the cast were sat at their desks and acting as though they were working inside a large glass box, which certainly caught the attention of passers by.

Sadly, poor Adam Scott suffered from one of the primary perils of live theatre after a bystander said he 'accidentally messed up one of the computers and tried to stay in character while fixing it'.

Observers saw the actor trying to sort out his retro looking computer after the screen gave him the 'no signal' prompt, and it's hard to stay in character while you're figuring out which cable isn't plugged in properly.

It's even harder to do when you know everyone is watching you, as a sizeable crowd gathered on all sides to watch Scott sort out his computer.

Scott was joined in his acting cube by co-stars Britt Lower, Zach Cherry and Patricia Arquette who join him in the second season of the critically acclaimed show, which releases at the end of this week (17 January), and has already been given the thumbs up by reviewers.

Director and producer Ben Stiller was on hand to film some of the best bits, including the cast cleaning the floor of their office and making paper planes to throw at each other.

In case passers by didn't know what this was all for, the big box had Severance printed on the side just so the large crowds gathered knew where to go to watch more.

The show has been described as 'one of the best TV shows ever' and a lot of money has been going into it.

Our own review of the show actually declares Severance to be 'the best show on television right now', and that's the view of someone with a chuffing comprehensive knowledge of TV shows (albeit with a bit of a blind spot where Peep Show is concerned).

"Severance does what Breaking Bad, Succession, Goodfellas, The Wire, and every other contender for the best show ever did – it improves and elevates everything it introduces in season one," our reviewer wrote.

The second season of Severance releases on Apple TV+ on 17 January.
