Paul Rudd, Carrie Coon, McKenna Grace and Finn Wolfhard reprise their roles as a family and team of ghost catchers in Ghostbusters: Frozen Empire – this time in the location of the original films, New York City.

The latest addition to the movie franchise sees the original and new generation team up to protect their home from a second Ice Age.

Here are the key things you need to know about the fourth outing of everyone’s favourite 80s ghost hunters.

Ecto-1 or Millennium Falcon?

There wouldn’t be a Ghostbusters film without the iconic Ecto-1.

In the first reboot, Afterlife, the car was found by Wolfhard’s character on the grounds of his late grandfather Elon Spengler’s farm.

With the help of Spengler’s ghost, they repaired it and in Frozen Empire, it returns to the streets of New York.

“I actually got to drive it, it was really unreal,” says Rudd, admitting it was a “tricky” vehicle to manoeuvre.

“It’s almost like you’re driving the [Star Wars spacecraft] Millennium Falcon.”

The Marvel star says that despite this being his second film in the franchise, the excitement never goes away.

The production used two versions of the car for Frozen Empire – remaking one with a Corvette engine for the high-speed shots.

Wolfhard says it was “insanely powerful”, but would constantly overheat and choke as they began to film a scene.

Ghostbusters cast’s friendships

Filming for the new movie took three months, and Rudd says the majority of downtime for the cast was spent together “without mobile phones”.

The Proton packs were so heavy that the crew installed pieces of wood for the cast to rest them on between takes and it gave them the perfect opportunity to get to know each other.

He says he would constantly ask for stories from the originals about the first film.

He has one stand-out memory of Ernie Hudson… his choice of treat.

“Ernie would always have those Tootsie Pops he loved – he had a real sweet tooth,” explains Rudd.

Hudson thinks it’s hilarious that that’s what Rudd remembers of him and adds it was simply to “fight the hunger urge”.

Ghostbusters and Finn Wolfhard’s directorial feature debut

In between filming for Ghostbusters: Afterlife and Frozen Empire, Wolfhard made his directorial feature debut with Hell of a Summer.

The comedy-horror premiered at the Toronto film festival in September last year.

His co-director Billy Bryk also featured in the first reboot as Zahk and the duo began writing the script during its production.

“I’m so in my head now”, says Wolfhard who thinks that going behind the camera has given him some new advantages and disadvantages when it comes to acting.

“I’ll see a scene in my head, I’ll think about what I look like in the future on screen and go, ‘God, you’re such an idiot right now’.”

Jumping into the conversation, Rudd reassures his co-star, calling Wolfhard a “terrific actor and a great director,” but insists that the insecurity around filming never goes away.

‘It crosses a generation’

The first Ghostbusters film was released in 1984 and starred Bill Murray, Dan Aykroyd, Harold Ramis and Ernie Hudson.

Eddie Murphy was originally intended for the role of Winston Zeddemore but he turned it down to do Beverly Hills Cop.

The role instead went to Hudson who says people still come up to him on the street quoting his character.

Hudson tells Sky News: “In the first Ghostbusters, because the part had been cut down from what the original part was, the guys all sort of came together and gave me a lot of the really good lines.”

The most common quotes he receives are: “It’s a big Twinkie”; “If there’s a steady pay check” and “If someone asks if you’re a God, you say yes.”

The 87-year-old actor says the franchise has always had its fans at the centre – something he believes is responsible for its continued success.

“It crosses a generation and the wonderful thing about Ghostbusters for me is you see a lot of sort of remakes or reboots or sequels, but a lot of times you get the feeling that it’s something the studio wants and not necessarily the fans, you know? But, this is one that I feel like the fans are asking for”.

The American actor says he was delighted to rejoin the cast and crew for Frozen Empire.

The new Ghostbusters’ film is just under two hours long.

And it does have an after-credits scene which suggests this might not be the last we see of the franchise.

Ghostbusters: Frozen Empire is in cinemas now.
