Actor Leonardo DiCaprio says his latest film Inception works on multiple layers simultaneously and is a “complicated” movie.

“It is complicated. It’s a complicated story structure, but it’s sprung from the great filmmaker Christopher Nolan’s mind, but he’s been able to take highly complex jigsaw puzzles in a narrative and put them together like we’ve never seen,” quoted DiCaprio as saying.

“Everyone’s going to be in for a treat when they see it, including me. This is a plot structure that’s working on multiple layers simultaneously — and quite literally when I say simultaneously, I do mean multiple narratives simultaneously,” he added.

The film also stars Marion Cotillard and Michael Caine.
