(AFP)Sanjay Dutt says Bollywood is not united anymoreLooking back at the early years of his career, Sanjay said the film industry once operated with a stronger sense of community.

It's sad, but I hope it comes back."Sanjay then compared Bollywood’s unity with that of Hollywood, where he believes industry bodies and artists stand together more strongly, saying, “In Hollywood, everybody is together, they are friends. It's competitive, but it's very healthy. Over there, everyone is very united. The actors are together, the writers are together. There are industry bodies that support everyone. Even at the Oscars, there's so much togetherness. Whenever an actor goes up to receive an award, there’s no jealousy. You can genuinely see everyone celebrating each other. It’s beautiful.”Recently, Sanjay reunited with his longtime friend and superstar Salman Khan.
