At this point, the definition of the term “fairy tale” is essentially, “An animated movie made by the Walt Disney Company.”
Here’s every single fairy tale movie we could track down (that we’re not sure isn’t dead).
Beginning in 1937 and running more or less to the present day, Walt Disney Animation began to turn many of these classic tales into feature films.
This means that not only are there more fairy tale films in development than you can count, in several cases, there are multiple studios working on the same property.
