I saw this movie before 2004 or 2005 and it takes place in a forest or woods and a group of people are running away from this monster type thing that was also like a ghost. It is green and hides in the trees. There’s a lady who is stuck under something and her leg decays to where there is just bone and I believe this part takes place in a crashed plane but maybe not. Another part is where they dig a hole either hiding from the monster or trying to find it. I remember one girl or woman looked in the hole and the monster was there. They may have also been trying to get a picture of it. This an English movie in color that is most likely american as I watched it in America. Thanks!
