Around half way through the movie when Catherine Zeta-Jones is dancing with Antonio Banderas, the camera shows the pair do a dance move, it then cuts to Don Raphael looking at them in Disgust:
Guess what, they are doing the exact same move as they were doing before......
A lot of dances (cultural or not) do in fact have repetitive moves. It doesn't mean the dance is any easier or make that scene false in any way. In the event that they did in fact reuse a scene, is it really and truly going to bother you that much?
