The Lost actor said of his co-star: "I don't think anyone else could have done it - there's no one else."
He added: "Whenever you work, usually if something has a chance or the potential to be good it usually starts with a good script and I'm very happy with the script and Naomi is doing it and she's wonderful... I'm very much looking forward to shooting."
Naveen will soon be seen on the small screen in the Sky1 HD fantasy drama Sinbad, where he plays villain Lord Akbari.
He said of his character's eyeliner and costumes: "There was something sort of Keith Richards circa 1971 about that eyeliner.
"You don't get to do that very often - prance about and wear dresses."
