When you're as successful and well-known as Leonardo DiCaprio, finding a way to escape the specter of fame can often be a frustrating journey. Case in point: 

"I was in the middle of the rain forest in Brazil, where a naked Indian gentleman recognized me from 'Titanic',” the 35-year-old told the Herald Scotland. “That was one of the more surreal moments of my life.”

The actor is currently on a media tour to promote his new film "Inception" — and as a result, is getting handed some interesting questions regarding his environmental activism in film. 

When asked whether he would ever be interested in making a sequel to his 2007 environmental documentary "The 11th Hour", DiCaprio says that it's something he's looked into. “But that movie was very hard to do," he says. "We spent hundreds of hours in the editing room, trying to condense a lot of different thoughts into an hour-and-a-half format. I don’t know if I’ll do that again personally. Whether I’ll narrate something, I don’t know.”

In terms of approaching movies that carry a socially conscious element, DiCaprio says it's not the only thing that makes him interested in a movie.

"Those things intrigue me. If it does have a socially conscious element to it, if it does say something with validity about the world we live in, if it does have a comment on our modern world … that is an element of the script that I see as interesting and important.

"But there are also other elements. It’s got to be emotionally engaging. I’ve got to feel connected to the character. I’ve got to feel like the filmmaker is going to do a good job in portraying the stuff in an honest, interesting way. If all those parts aren’t there in the whole, I won’t be interested in a movie just because it’s got social commentary. It’s one part of a whole.”

"Inception" opens everywhere on July 16. So far, it's receiving rave reviews and trending an impressive 100 percent approval rating on Rotten Tomatoes.
