Mumbai, April 6 (IANS): Filmmaker Arbaaz Khan is not convinced about the idea of making a biopic on his brother superstar Salman Khan as he feels there is nothing new about Salman that he can show in the biopic.

The "Dabangg" filmmaker, when asked if he'd make a biopic on Salman's life, said: "It may happen, but personally I would not want to do a biopic on somebody who is existing."

He sees no point in a Salman Khan biopic.

"Generally, the biopics are made on the personalities about whom much is not known. But if someone who is already popular and everyone knows about his life then I don't see a point in making a biopic on his life unless you are telling something new about that person," Arbaaz said.

Further, talking about a biopic being made on Indian cricket captain Mahendra Singh Dhoni, he said it will be a challenge for its director Neeraj Pandey.

"I think Dhoni's biopic will be a big challenge for Neeraj Pandey because we all know about Dhoni and we all are excited to see what new will be showcased," he said.
