Does it remind anyone of The Emerald Forest??
This reminded me SO much of that movie. It's about 25 years old, and stars Powers Booth as a contractor clearing a forest in South America somewhere (I think). His son disappears into the forest one day, and most of the film takes up his search for him. For a moment, I thought that Vinyan would end the same way as the Emerald Forset. I won't give either endings away here now.
Anyone else agree with the similarities
