Aladdin and Mulan are already in pre-production and Disney already has a number of release dates set aside for additional adaptations over the next several years.
The Little Mermaid was the film that birthed the Disney Renaissance so there are about as many fans of that one as there are for Beauty and the Beast.
Beauty and the Beast is on track to have a huge opening this weekend and its success will only speed up the production of additional live-action adaptations.
