'Dabangg' director Abhinav Kashyap called Salman Khan "insecure" and claimed that he cut brother Arbaaz Khan's role in his 2010 movie. "These brothers hate each other...but I don't know why they live together. It's a very difficult family to understand," he said. "Once Arbaaz and Salman had a fight in front of me during which Salman threw utensils," Abhinav added.
