As Oscar season gets closer, new details about Alejandro Gonzalez Inarritu's "The Revenant" have been revealed.

In a roundtable with producers for The Hollywood Reporter, producer Steve Golin noted some of the biggest challenges for the film.

He said that one of the most interesting things that they did while shooting the movie was to wait for snow.

"The big nemesis we encountered was the weather. We faced completely unusual and unpredictable weather patterns. Before experiencing it firsthand, I didn't know what a chinook, a warming wind that quickly melts and evaporates snow away, was," he said. "We would come to work and have beautiful snow, and then you'd go in the trailer and come out an hour later to completely dry ground. It was shocking. It was as though someone came and sucked up everything with a vacuum cleaner. We were shooting in Calgary, and March, which is traditionally their heaviest month of snow, was suddenly just the opposite."

Since the snow kept melting Golin noted that they had to find ways to get the snow back in the scene. The producer noted that they started using snow machines but even those did not work because the temperatures would rise and melt it away.

Golin added that the way the film was shot was one of the most ambitious things he has done in his career.

Emmanuel Lubezki was reported to have shot the whole film with natural light, a trick he used for Terrence Malick's "The Tree of Life."

"The Revenant" has been publicized for the brutal conditions on set as many people walked off the production and the budget rose from $90 million to over $130 million. Leonardo DiCaprio also stated that it was one of the hardest things he ever did but was aware of the difficulties he would go through.

Additionally, Tom Hardy was forced to quit "Suicide Squad" once production had been delayed.

The film, which is still in the editing room, is expected to be an Oscar player come December.

Many pundits are already pinning DiCaprio as the front-runner to win the Oscar for Best Actor and the film is also being considered a major Best Picture contender. Many expect the movie will also be a big box office hit but it all depends on how critics end up receiving the movie.

"The Revenant" also stars Will Poulter, Domhnall Gleeson, Paul Anderson and Lukas Haas. The film is expected to be released in limited theaters on Dec. 25 and expand nationwide in January.
