Christopher Nolan, the director of ‘Inception’, is all praises for Leonardo DiCaprio’s demanding nature during the making of the film.

He said in an interview that Dicaprio’s exacting standards helped him work out where in ‘Inception’ the emotional importance of the story is.

Nolan said that he always wanted to work with the 36-yer-old star and was delighted when he agreed to appear in his movie.

Christopher said: 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.”

Both Leonardo and Nolan are known to stick to the same set of people to work with. Christian Bale has been a favourite with Nolan he has worked with him in three projects.

Leonardo has had a tremendous year career wise in 2010. He is the highest earning Hollywood actor with two biggest box-office draws to his credit-‘Inception’ and ‘Shutter island’. Leonardo gets innumerable movie offers but he says that he has pretty high standards when it comes to agreeing to do projects.

He explained: I want it to be special and really original. For me, the three elements there have to be are; it has to be a great script, with a great director and great people to work with. That's what I want and I guess it would sum up the dream for any actor.

He has made the right career moves and his choice of scripts has been exceptional. His partnership with Martin Scorsese has seen him act in ‘The Aviator’, ‘Gangs of New York’ and ‘The Departed’ and ‘Shutter Island’. He is planning a biopic on Frank Sinatra with him.

Nolan himself is no mean director. He has critically acclaimed films, ‘The Prestige’, ‘Insomnia’ and ‘Batman Begins’ and ‘The Dark Knight’ to his credit. For him to credit Dicaprio with helping him in finding the emotional quotient for the character in inception is indeed high praise for Leonardo.
