Sophia Myles has revealed she still can't believe she has a role in the next Transformers film.
The British beauty is to play a scientist in Michael Bay's fourth instalment of the giant shape-shifting robots franchise alongside Mark Wahlberg and Stanley Tucci.
"We've been on it for a couple of months now. It's so exciting and so thrilling. I love working with the whole cast and Michael Bay is just an incredible director. I feel so privileged, I'm still pinching myself," she said.
"We're still shooting right now. We've been all over the world: we've been in Detroit, Chicago, Washington, Texas and a lot of it in Hong Kong and maybe parts in China."
Sophia remained tight-lipped about her character but admitted she hasn't filmed with Mark yet.
"I haven't actually worked with Mark yet but I have lunch with him and his entourage whenever we're on set. They're the most hilarious people I've ever met," she continued.
"A lot of my work is with Stanley Tucci and he's just so funny. He's so talented and I have to not laugh at him being incredible, and that's one of the hardest things I've had to do on the film."
The former Spooks star did admit that the forthcoming film will be "even better" than its predecessors, which starred Shia LaBeouf.
"I think it's going to be even better than the last ones and they were pretty great," she said, adding: "We've all been sworn to secrecy. I'd love to tell you more but I can't."
Kelsey Grammer, TJ Miller and Li Bingbing will also star in Transformers 4, which is set for release in summer 2014.
