I watched this movie when I was in elementary so it was probably made in the 2000s…I might’ve watched it around 2007? Anyways, the small parts I remember is that there were a bunch of kids going to a…private(?) school and every kid there was going to be harvested. The teacher’s weren’t supposed to tell the kids what was going to happen to them but one teacher did. Some kids ended up running away. I’m not sure what happened after that but I do remember one of the main characters running into a hospital to get his friend, but her organs were already harvested. She was still walking around though, the hospital took the children’s organs slowly not all at once. So the main character and his friend tried to escape. That is all I can remember. The film is in color. This has been irritating me for years, especially ever since Neal Shusterman wrote Unwind. The book reminds me of the movie.
