London: Hollywood superstar Leonardo DiCaprio, who plays a skilled thief who steals secrets from people`s minds in `Inception`, finds dark films "exciting".
The `Departed` star plays the role of Dom Cobb, the Extractor in the sci-fi thriller directed and produced by Christopher Nolan, the Independent reported.
"I find these types of films that are psychologically sort of dark at times extremely exciting to do because there`s always something to think about," he said.
The 35-year-old star said his upcoming film `Inception` was so deep that when he initially read the script, he didn`t understand it.
"I didn`t understand the script at first. 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?
"There`s nothing more boring than showing up on set, saying a line and knowing that your character means exactly what they say," he added.
The film releases on July 16.
