And what they believe in real life is complicated. Theodor Koch-Grunberg wrote in his diary that indigenous peoples in the Amazon see these outsiders following in each other's footsteps as the same person, a single soul traversing across several lives. They also see time as something that doesn't proceed inexorably into the future.

If you think we are going to gain ground by holding the American people hostage, saying that their taxes are at risk, I actually disagree.

The two explorers are given fictional names. But as in real life, they travel to the Amazon roughly a generation apart, in the early-to-mid 20th century. In the film, they're both guided by Karamakate, as a young man early in the story and later as an old shaman. He and the outsiders share a desire for knowledge - self knowledge and an understanding of the world around them, says the film's co-screenwriter, Jacques Toulemonde.

Both the old and young Karamakates are portrayed by indigenous men, neither of them professional actors. The old shaman is played by Antonio Bolivar Salvador.

In fact, Guerra based his story on the diaries of two explorers, German Theodor Koch-Grunberg and American Richard Evans Schultes. There work is some of the only documentation of cultures that have since vanished. But Guerra did not want white men to be his protagonists.

I'm against tax increases on anyone, period, end of debate.

"Embrace Of The Serpent" has been a big deal for Colombians outside the Amazon. It's been showing continuously there for more than three months. And the Oscar nomination, the film's producer says Colombians are comparing it to having the national team in the World Cup.
