The Visitor(2012)

A small boy is left alone to play in a large and empty house. A dark cloud starts to seep in from behind the mail slot at the front door. As it fills the space, a monster forms. The boy runs away, but the creature is always near. The chase will not end until the boy discovers the source of his fears. The film uses a combination of 2D hand-drawn animation, 3D backgrounds and particle effects. This film was made as part of the 8th edition of the NFB's Hothouse apprenticeship.
