When Marilla shows Anne to her room on her first night at Green Gables, Megan Follows enters the room and when she does her hat brushes Colleen Dewhurst in the face. When Colleen Dewhurst turns toward the camera, you can see her barely holding in her laughter. According to Kevin Sullivan, Dewhurst was renowned for her practical jokes, and she did something in the room as a joke on Megan Follows. Sullivan could not recall exactly what Dewhurst had done. This is the reason why she's trying to hold in her "laughter".
