Brad Pitt takes big 'risk' for upcoming movie

Brad Pitt is set to appear in Heart of the Beast. It’s a survival adventure film.

For this, the Grammy winner is notching up his prep even to the level to match his co-star Leonardo DiCaprio in The Revenant.

It is well-known that the Titanic star went to great lengths for the role, winning him an Oscar. So, the Fight Club actor wanted to challenge himself similarly.

An insider told In Touch, "Of course Brad is competitive enough to want to top what Leo did. But even matching that level of extreme physicality would be remarkable, and not without real risks.”

The source continued, “Brad is going into Heart of the Beast with his eyes wide open as a producer, a star, and somebody who is going to be putting himself through an enormous amount of physical punishment to get this story told."

The film tells the story of an ex-U.S. Navy Seal stranded in the North American wilderness with his retired combat dog.

Sources say the Fury star did not like going to the gym. Still, "he’s been doing as much outdoors training as he can, putting his flexibility and endurance to the test."

“This movie came together quickly, but Brad has been quietly amping up his workouts with the specifics of this wilderness adventure in mind," the bird chirped.
