The Lost City of Z

While filming in the jungle, Hunnam remembers a particularly nerve-wracking encounter one Saturday night following an exhausting six-day shooting week. "I was staying in this little shack on this hill and woke up at three in the morning to this ungodly noise, like there was a pneumatic drill in my ear. An insect had burrowed into my ear and hit my eardrum so it couldn't go any further. It was a long beetle with wings. When it couldn't get back out, it kept trying to burrow further in and flapping its wings. That's what woke me up."

In many of the scenes the party is going visibly downstream while they are searching for the origin of the river.

Near the end of the credits, jungle noises resume.
