Jean Coralli and Jules Perrot designed the dances for "Giselle". Perrot and Carlotta Grisi were lovers, and Perrot designed all of Grisi's dances and all of her pantomime. Everyone in the Paris dance world knew that Perrot had designed Grisi's dances, and Coralli said so, but Perrot was given no official credit in the printed materials such as posters and programs. This was most likely done to prevent Perrot from collecting royalties (money, profits) on the ballet. Perrot liked bold touches and planned several rapid aerial swoops on wires in Act 2 for Giselle. Grisi was afraid of these swoops. A stage hand was brought in to test the swoops. He crashed face-first into the scenery. The swoops were abandoned.
