Russell Brand wants to take a break from acting and focus on his stand-up comedy show, 'BrandX.'

The comedian has admitted that her feels ''unfulfilled'' starring in movies such as 'Rock of Ages' and 'Arthur'.

He said: ''I started to feel a little bit unfulfilled. I missed being around an audience, I missed being really honest and truthful.''

But the 37-year-old star admits his career Evolution was only natural.

He said: ''People went, 'Do you want to star in movies?' I went, 'All right, I'll try all of that.' But now I know what 'that' is, I think I'll just get cast in things once in a while.

''Having investigated it, I now think, 'No, stay true to what it is you actually do and what you're supposed to do.' And that is comedy, about things that are challenging and unsettling but ultimately very warm and loving.''

He added to The Sunday Times' Culture magazine: ''I'm going to continue to make films because I think they're prestigious and they can be really enjoyable. But I suppose as an artist you want to be engaged creatively by what you do in a real way, so yeah, certainly I feel more directly engaged by this show [BrandX].

''I just want to do something that's really, really authentic, that hasn't got any nonsense to it. I'm saying what I believe in--and then we can work it out and cut out the things that are too mental and unbroadcastable.''
