At the start of the film Mia (the girl) is watching the circus. As the Ringmaster says "Welcome to Circus Marvelous" the Dwarf, that is standing in front of the Ringmaster, holds both his fists in front of him in a power pose. The very next shot he has his left fist in the air while his right is still in front. Then in the shot after that both of his fists are in front of him once again.
Throughout the film, you will notice that the main character, Mia's leggings beneath her dress change colors. In certain scenes, she is wearing dark leggings, and in other scenes she is wearing light.
