The actor admitted to Flicks and Bits that it was not easy leaving home to shoot the film in New Zealand for an extended period of time.
"It was daunting because you knew that the duration of it, of filming, was going to be so long, and the distance away from home was so far," Freeman explained, adding: "That was the daunting thing for me."
Freeman went on to say that he felt less nervous about playing JRR Tolkien's iconic literary character Bilbo Baggins, given his approach to acting.
"The actual responsibility of playing Bilbo Baggins, I obviously took very seriously, but I always take everything seriously," he said. "And in New Zealand, filming, they make it so that you don't feel like you're entering Death Row or something.
"Their attitude is that it should be fun and it should be something that you play, and that's how you're going to do your best work. So that didn't really feel scary."
