Movie fans have not been short of either comic book adaptations or spy movies in recent times yet when Kingsman: The Secret Service hit cinemas three years ago its sharp script, bags of humour and fizzing energy ignited a passion in audiences.

Now they are back – once again scripted by Jane Goldman and directed by Matthew Vaughn – and ready to take things up a notch again.

The movie, out on Wednesday (September 20), sees Colin Firth and Taron Egerton’s Kingsman under threat from the evil Golden Circle, led by an evil mastermind played by Julianne Moore.

To survive, they need to seek help from their American counterparts, known as the Statesmen.

Taron Egerton was plucked from obscurity to play Eggsy, the teenage Millwall fan chosen by Colin Firth’s Harry Hart to be part of an immaculately dressed and gadget packed secret service called Kingsman.

Speaking to the crowds at the film’s World Premiere in Leicester Square on Monday night, he said: “When we did the premiere three years ago, I was just focussed on not falling over. I remember being so, so nervous and so excited as well. It was the first film I had ever done.

“And I was with Matthew (Vaughn, the director) and Colin Firth and Mark Strong and Samuel L Jackson and Michael Caine – and I knew it was going to be something special.

“I am so glad it was enough of a hit to warrant coming back. And I don’t know if you have noticed but we have actually assembled a little known rabble of actors to join us this time.

“It is so exciting to be here, I’m very proud of the movie and I don’t think anybody is going to be disappointed.”

The ‘little known rabble’ Egerton refers to is in fact a galaxy’s worth of stars, including but not limited to: Julianne Moore, Halle Berry, Channing Tatum, Jeff Bridges, Pedro Pascal, Poppy Delevingne and Elton John, playing himself in a cameo.

For Jeff Bridges, the chance to join the cast for the sequel was ‘a no-brainer’. He told the crowds at the premiere: “That first one knocked me out. Those guys, they really knocked it out of the park.”

While the movie is packed with huge stars, there was also space for some newer faces. Hollyoaks alumnus Calvin Demba plays lead character Eggsy (Taron Egerton)’s mate Brandon.

He said: “It was a really good experience for me. I’m very fond of Matthew Vaughn’s work and obviously working with Taron Egerton was pretty cool as well.

“I’ve never really been in a big budget film like this so was a bit of a revelation to see how these guys work.

“Everyone was really focussed and sure they were onto something big and it was nice to be included in that.”

Kingsman: The Golden Circle is released in cinemas on September 20.
