Sikhism and Bollywood

Have you ever seen a Bollywood movie that has a Sikh character? Probably, Yes. But, Have you ever seen a Bollywood movie that has a Sikh character who really is a Sikh? Now that's impossible. No matter a Bollywood movie has a Sikh character as the main actor, a side actor or in a very small role, Bollywood never presents it correctly. Every movie that comes out with actors playing Sikh characters, will have Sikh sentiment hurting scenes. Why is it that every movie shows the wrong picture of the Sikhs?
