Good news for Kingsman fans: Taran Egerton says the forthcoming sequel is “going to be incredible.”

Speaking at the PEOPLE / EW / InStyle Portrait Studio at the Toronto International Film Festival on Saturday to promote his voice work in the animated film Sing, Egerton teased Kingsman: The Golden Circle, the sequel to 2015’s sleeper box-office smash Kingsman: The Secret Service.

“Doing Kingsman is such hard work. It’s so physical and demanding. It’s brilliant and you don’t resent a moment of it because I believe [director] Matthew Vaughn is an incredible director and I have every faith it’s going to be a great movie,” he said. “It’s so challenging. Luckily, you’re surrounded by an incredible team. The best stuntmen in the world. The cast is incredible. The cast in the sequel is … it’s insanity who I’ve acted opposite in the past six months. It was tough, but it’s going to be incredible.”

About that “insanity”: The Kingsman sequel, which is out next year, stars original actors Egerton, Mark Strong, and Colin Firth, along with newcomers Channing Tatum, Jeff Bridges, Julianne Moore, Halle Berry, and Sir Elton John.

The first film grossed $414 million worldwide, including $128 million in North America. Kingsman: The Golden Circle is out June 16, 2017.
