Leonardo DiCaprio says the extreme conditions while filming Fox’s "The Revenant" meant that "It was the most difficult film, I think, that any of us have ever done."

The actor made his remarks Monday night at a Q&A session following the screening at the Academy’s Samuel Goldwyn Theatre in Beverly Hills. Fox unwrapped the film, one of the year’s most anticipated, for guild and media members at several screenings Sunday and Monday.

DiCaprio said they rehearsed like a stage production for a long time, since the camera moves were intricate and they often had only 90 minutes a day to capture “the beautiful, illustrious Chivo light,” a reference to d.p. Emmanuel Lubezki.
