The makers of original Don, starring Amitabh Bachchan had earlier slapped a legal notice at the producers and dragged Excel Entertainment, Red Chillies and Reliance Entertainment over copyright issue.
"About the notice from the original producers of Don, be rest assured that we have done nothing wrong and shall stick to the correct legal and moral principals," producer Ritesh Sidhwani wrote on twitter.
If we remember Shahrukh's last movie Ra.One, it faced the same issue. TV producer Yash Patnaik had moved the court claiming that much-anticipated sci-fi film Ra.One was conceptualised by him. The script writer alleged that Ra.One producers had copied his idea of an Indian superhero and thus violated the copyright act.
