Salman Khan's production venture "Hero", which is slated to release on 11 September, could face trouble because of a complaint registered against the superstar and the film's co-producer Subhash Ghai.

Reports suggest that when the makers announced to remake Ghai's "Hero" (1983) that starred Jackie Shroff and Meenakshi Sheshadri, the family of late Ram Kelkar -- the scriptwriter of "Hero" -- was allegedly promised a royalty, but is yet to be paid.

With just a few days to go for the film's release, Kelkar's family had no option but to file a complaint against the duo with two film associations.

"Kelkar's family was assured a royalty payment when Salman and Ghai announced Hero's remake. The upcoming film's promo has long been released, but the promised dues have not reached them yet." Bollywood Life quoted a source as saying.

Directed by Nikhil Advani and co-produced by Salman and Ghai, "Hero" will mark the debut of Sooraj Pancholi, son of actor Aditya Pancholi and Athiya Shetty, daughter of Suniel Shetty.

The film also has Govinda and Vinod Khanna in important roles; Salman makes a special appearance. 

The "Bajrangi Bhaijaan" actor has also sung the title track of "Hero" that has garnered huge response from music lovers.
