Russell Brand is completely "eccentric".

The British comedian is known for his wacky ways but 'Get Him To The Greek' co-star Rose Byrne says his strangeness would not stop her from working with him again.

Australian actress Rose told Live magazine: "I become hysterical with laughter on set - particularly when I'm tired. Working with Russell Brand was a challenge - obviously his reputation precedes him. You never know how he's going to be, and you're working with someone who's had many interesting 'incidents'.

"Thankfully he's got an off switch, so when we were working there was some laughter, especially during the improvisation, but he was pretty focused. Yes, he's eccentric, but I would work with him again in a heartbeat. He has lovely people around him too, a great team, which I think says a lot about a person."

Rose also hit it off with her 'X-Men: First Class' co-star James McAvoy because of the "cultural affinity" between Britain and Australia.

She said: "I think there's a cultural affinity between the British and Australian people because of our history. Maybe that's why James McAvoy and I had a good laugh on the set of 'X-Men'."
