Having recently completed filming on 'The Lost City Of Z' with co-stars Sienna Miller, Robert Pattinson and Tom Holland, Charlie Hunnam has opened up about the way he and his fellow actors worked on the movie's set. Though his relationship with Miller seems the standard type of kinship actors share when they're working together, his time with Pattinson (and to some extent, Holland) was a little stranger.

He said: "I had a couple of rehearsal sessions with Sienna, but I didn't spend any time with Tom or Robert. I wanted these relationships to evolve naturally on screen. Through the work, I don't think I said more than ten words to Robert [Pattinson] off camera.

"I didn't know if he was just 'in that zone' or if he genuinely didn't like me. There was a real distance between us. But it creates the right dynamic on screen. He's reached out to me subsequently, making overtures for us to be friends now, so I think it was about the work."

Speaking to ScreenDaily.com at the Berlin Film Festival, the actor also spoke about some of the biggest challenges that came with filming in the Amazon: "In addition to a large beetle getting stuck in my ear, the most dramatic experience we had was when we had to evacuate because of the thunder and lightning. The first time the river was rising rapidly, and we couldn't sail down the river, so instead we had to hike through the jungle in the middle of the night to get to base."

Pattinson plays the aide-de-camp, Henry Costin, while Harry Melling, Franco Nero and Ian McDiarmid also star.
