Mary Bunting is sitting alone when to her surprise and delight a rabbit six foot tall - elegantly dressed in frock coat and fancy waistcoat - appears. As he is a magic rabbit, he can be seen only by Mary, which naturally creates great confusion and misunderstanding.
Unfortunately the movie Mr. Horatio Knibbles is not yet available on HBO Max.
