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."
