Leonardo DiCaprio confessed he did not understand the script for his sci-fi motion picture, Inception.

The actor said the storyline was so deep that he could not make sense of it when he first read it.

"I didn't understand the script at first," he said. "Films should make you extract your own meaning or have different interpretations of an ending. Some things will always be uncertain. And isn't all this part of the experience of going to see a film?

"When it's done properly and you don't lose the audience, I think they are completely engaged and happy to unlock some of the answers.

"If I go to a film and there's no discussion after, that makes me think it's pretty sh**ty."

DiCaprio's performance as Dom Cobb is already generating Oscar buzz.
With Memento and The Dark Knight director Christopher Nolan and an award-winning supporting cast giving him a one-two punch, the actor has high chances of finally getting an Oscar.

The Titanic star has been nominated for the Academy Award three times for films What's Eating Gilbert Grape, The Aviator and Blood Diamond.
Inception is scheduled to be released in theatres July 16.
