Laughton drew on the harsh, angular look of German expressionist films of the 1920s, which is especially noticeable in the art direction by Hilyard Brown. He had the idea that children notice only certain details of their surroundings that they are focused on, which is why some set pieces are somewhat abstract and minimal: neon lights that aren't attached to a particular store, white picket fences that are not surrounding any house, the barn along the river that looks like a painting, and the "chapel-like" parents' bedroom. The river scenes with the children were all shot on a sound stage. The shot of John looking out of the barn window and seeing Powell's silhouette on the horizon was created using a little person and a miniature horse. The underwater scene showing Willa's dead body was shot in a studio using a mannequin with a custom mask to make it look like Winters.
