What is the name of that horror movie with the tree baby that eats people? I have not seen it in years and can’t find anything about it anywhere on the internet.
Could it be Greedy Guts (2000)? The original title of the film is Otesánek. It’s a Czech film, sort of a comedic horror.
A woman learns she cannot have children. Her husband, in an effort to comfort her, takes a tree root and makes it into a child.
The woman is rather unhinged and pretends it’s real. So much so, the root comes to life and needs a great deal of fuel in order to keep growing. That fuel happens to be people.
