Alejandro Gonzalez Inarritu’s follow up last years Oscar winner “Birdman” is the upcoming “The Revenant” starring Leonardo DiCaprio and Tom Hardy. The trailers so far look nothing short of spectacular, with the shots looking more akin to a real event unfolding in front of our eyes than a motion picture.

This huber realistic look is partly down toInarritu’s insistence of using only natural light and filming in real extreme locations. DiCaprio has been speaking to Yahoo Movies where he talks about how difficult and extreme the shoot was and how different the film is from anything audiences have seen before:

“It’s going to be one of the most unique film-going experiences that audiences have seen in modern times. I can name 30 or 40 sequences that were some of the most difficult things I’ve ever had to do. Whether it’s going in and out of frozen rivers, or sleeping in animal carcasses, or what I ate on set. [I was] enduring freezing cold and possible hypothermia constantly… [Inarritu is] vigilant and incredibly specific about what he wants up on screen, and he won’t accept anything less.”

With oscar contenders like “The Revenant” and Quentin Tarantino’s “The Hateful Eight” all competing with the mega blockbuster Star Wars this December, DiCaprio believes there is room for at the box office for both types of film.

“There’s always room at the top. I’m going to be in line for ‘Star Wars’ as well. What’s great about this time of year is, as you know, they save the best for last in most cases. And hopefully, it just means more people are excited to go to the movies. I think that people know this time of year is where a lot of great pieces of art are going to come out. I would never think that we’d be able to compete with ‘Star Wars’—that’s something that’s embedded in our cultural DNA. But I think when people begin to hear about this movie, they’ll want to go see it. And that’s all we can hope for.”

“The Revenant” Opens Christmas Day. Check out the spectacular trailer below.
