Django Unchained star Leonardo DiCaprio has said that is planning on taking a significant break from filming to concentrate on his environmental campaign.

In an interview with a German newspaper, Bild, the 38-year-old Titanic star said: "I am a bit drained. I'm now going to take a long, long break. I've done three films in two years and I'm just worn out."

"I would like to improve the world a bit. I will fly around the world doing good for the environment."

DiCaprio recently filmed The Great Gatsby and The Wolf of Wall Street.
