Disney Mothers

A reoccurring theme in most Disney films is that most of the protagonists in their respective films don't have mothers. A common guess as to why this happens is that in the early 1940s, Walt bought his parents a house as gratitude for them taking care of him. Unfortunately, there was a major gas leak in the house which resulted in the death of his mother. Walt felt personally responsible for this tragedy, and it is believed that he subconsciously put that plot point into most of his films.
