One moment in the movie shows Taron Egerton’s Eggsy tasked with placing a tracking device inside Clara’s (Poppy Delevingne) private area; a scene that has generated a fair share of the film’s discussion due to its use of CGI and the fact the viewers are taken literally inside the female character.
Vaughan, however, has said it was another scene altogether that was his most challenging.
That accolade, it seems, goes to “the opening taxicab fight”, he told Vulture. “That opening scene was very difficult.”
However, he quipped: “The scene with Eggsy trying to place a bug into a person was incredibly hard to shoot as well. And just making a sequel. By the way, the whole thing was very hard. This was the hardest movie I’ve ever made.
“I’s not easy making sequels. What’s hard about making a sequel is people see a sequel expecting to see what they liked in the first film, but if you do too much of what they liked in the first film, you’re boring and unoriginal and repetitive.
“It’s a balancing act, so that was hard.”
He went on: “Actually, and the [ski] gondola sequence was hard. We went out in the mountains and a lot of people had altitude sickness, so that was difficult making it with half the crew who couldn’t stay up there.”
Kingsman 2 has had a strong performance at the box office so far, topping the list in the US last weekend.
Reviews have been a little more lukewarm this time around, however; with the consensus not as strong as it was in 2014 for the first film.
Alongside Egerton and Delevingne, the likes of Colin Firth, Julianne Moore, Sir Elton John and Halle Berry also star.
