Trivia: When King Triton enters the concert hall and passes over the audience, you can see Mickey Mouse, Goofy and Donald Duck sitting among the audience. (00:03:33)
Trivia: In the open-matte print, right after the credits, the support beams of the movie lot walls are visible, painted in blue to simulate the sky.
