Wendy’s Nightgown
Peter Pan is full of magic, but here we’re pretty sure the nightgown wasn’t supposed to be a magical one that changes color. We’re talking about the scene when Wendy is singing Michael to sleep with a beautiful solo of Your Mother And Mine.
At first the nightgown is light blue, but then right as she is laying him down, it turns white. And then before you know it, it’s blue again.
But, we’re gonna give them the benefit of the doubt here. Peter Pan was made in 1953, when animation techniques just weren’t what they are today.
