Its an old movie1986-1996.Im trying to remember the title a long time now but no luck,,,Its starts with a crushed spaship in the woods of an exoplanet. I remember that inside the spaceship was a little boy, a man and a woman,they were all wearing white .They had a green herb for when they were injured There is a scene with a huge giant with long hair and a club on his hand who captured the family into cages made of rope from the ceiling inside a cave and they escaped somehow...
