The former Spider-Man actor researched his role as real life pacifist soldier Desmond Doss in Mel Gibson's film by visiting the American hero's home in Chattanooga, Tennessee, and while he was there he felt the need to call on his character's spirit to help him capture his essence.

"I went onto his old property and went into his woodshed and handled his tools and walked around the lake," the British actor tells WENN. "I spent a day there just kind of praying and asking him to guide me through this.

"I said, 'If you can hear me, tell me what to do, tell me how to move, tell me how to speak, tell me how to behave and I'll do whatever you say'."

"There was a strange mystery of spirituality going on around the making of this film," he adds. "It was a long process to get Desmond's story out to an audience, to make ripples further into the world. His story will create ripples in the lives of others that see this film."

And his hard work paid off - director Gibson was so impressed with the Brit, he wants to work with him on every one of his films.

The Braveheart filmmaker says, "Andrew inhabits the character perfectly and he did such a good job, I'm really proud of him. I'd like to work with this guy all the time; he's amazing."

Hacksaw Ridge also features Sam Worthington, Hugo Weaving, Rachel Griffiths, Teresa Palmer, and Gibson's own son, Milo. It opens in theatres later this week (ends04Nov16).
