Leonardo Dicaprio praises `Inception` director

London: Actor Leonardo DiCaprio is all praises for his director Christopher Nolan`s "highly ambitious" new movie `Inception`. "It`s a highly ambitious film and it works on four different states of the subconscious mind. It`s like a domino with each one affecting the other," a news website quoted him as saying.

The 35-year-old actor plays the leader of a gang of dream thieves in Nolan`s latest film. He loves the ideas behind the sci-fi movie and thinks the clever plot will give audiences something to reflect on afterwards. "It`s Chris Nolan delving into dream psychoanalysis and also making a high-octane, action-filled, surreal film," he said. The `Shutter Island` star also said filming the movie required a lot of "detective work" as he had no idea what it was actually about. "Chris wrote the entire thing and it all made sense to him, although it didn`t make much sense to us when we were doing it. "We had to do a ton of detective work to try to figure out what the movie was all about and what we were doing from day to day," he added. IANS
