So here is the first dancing scene, it's from the movie Mangal Pandey. The actress who is dancing in this part is Rani Mukherjee. I think her performance is great!

Sorry the video doesn't work... I've tried to post an other one but this one has the best quality... so clic on "visionner sur youtbe".
