Theo James doesn't enjoy being a celebrity.

The 30-year-old actor - who stars alongside Shailene Woodley in the sci-fi movie 'Insurgent' - has revealed that although he relishes performing in front of the camera, he doesn't enjoy the attention that comes with it.

Asked to name the trickiest part of being a movie star, Theo said: ''To be honest, one thing that's trickier is what's happening now with how connected we are globally is the blurring of the lines between being an actor as your job and being a celebrity. That is tricky.

''Some people embrace it, some people like and props to them if it works for them. But it can be a bit difficult because at the end of the day all this other stuff is irrelevant, acting is my job.

''You never want to perceive yourself through anyone else's eyes and whether that's the media of a social thing, or someone coming up to you in a bar. You want to maintain the fact that it's a job, that's what it is.''

But despite his fame, Theo thinks he's largely unaffected by the trappings of success.

He shared: ''I'm still the same person so it hasn't really changed me. It's not like I go to trendy parties, that's not particularly my thing, not that there's anything wrong with it.

''So I don't think it needs to change you unless you want it to.''
