Mekhi Phifer has claimed that Torchwood: Miracle Day is a "worldwide" series.
The actor told SFX that the sci-fi drama has neither an American nor British feel.
Phifer said: "I have never done a British show, so I don't have a frame of reference to compare it to. But the energy felt the same as any time I'm on a project that people really care about."
He continued: "It just felt like we were doing something good, which for me is what matters. It wasn't a British show or an American show or whatever. It just felt like we making something special that the world could grasp on to."
Phifer also claimed that he would "absolutely" return for a second series of Torchwood.
"There's no question about that," he said. "This is the first time since ER that I've felt that same family atmosphere."
