Continuity mistake: In the bedroom scene, when the camera looks out of the window at Alice, she's wearing a plain blue t-shirt with a denim jacket. After she's climbed in, it has writing on.
Continuity mistake: When the kids are gathered to film on the hill with the train crash in the background, Joe grabs the camera to get a closer look, setting up the tripod a couple feet away from Alice. Joe hunches forward to look through the camera. Then the group is shown from behind and Joe isn't hunched forward anymore. Alice is still a couple feet to the right and Cary a couple feet and forward to the right of her. When the camera comes back around to the front of them, Joe is hunched forward again, and Alice & Cary are right next to him. (00:32:00)juliebellp107
