Christopher Nolan praises 'demanding' Leonardo Dicaprio

Director Christopher Nolan has appreciated Leonardo DiCaprio for being 'demanding' on the Inception set.

Nolan, who was delighted when the 36-year-old actor agreed to appear in his movie, was even happier when he realised how dedicated the actor is.

"Leo is someone I had been trying to work with for years. I'd met him many times and nothing had come together, but I finally managed to convince him with this one and he brought an incredible amount of emotional focus to his character," Contactmusic quoted him as saying.

"He is extremely demanding, which actually helped me work out where in Inception the emotional importance of the story is," the director added.
