Taron Egerton thinks "the world" of Colin Firth.

The 27-year-old actor has praised his 'Kingsman: The Golden Circle' co-star and has admitted he even boasts a strong friendship with the 57-year-old actor off set as well as he will often text Colin to check in on him.

Speaking to Shortlist magazine about his colleague, the dark-haired hunk said: "I seek his company outside of work, I think the world of him, I text him and ask how he's doing."

And the star has hinted Colin does reply to his messages.

When asked how long Colin takes to respond, Taron said: "I suppose it depends if his phone's next to him. Or it'd take longer if he's doing his tie."

Meanwhile, Taron has revealed he tends to play heroic "good guys" in movie projects, but he would like his next role to see him cast as a character who is "less sympathetic".

He said: "They say a movie is only as good as its villains. I think that's often true. But I'm always playing good guys. I'm aware of it, it's something I'd like to do long-term. Not just play a baddie, but someone more morally ambiguous, someone far less sympathetic."
