Shah Rukh Khan, who bagged moolah following the success of his latest film ‘RA.One’ now, has a reason to worry. King Khan starrer ‘Don 2 - The Chase Continues’ which was slated to hit the theatres this Christmas has run into legal trouble.

According to Nariman Films, who produced the Amitabh Bachchan`s 1978 hit, ‘Don’ had only given Excel Entertainment the right to remake the film but not for its sequel. This has miffed the producers of the original film and they have sent a legal notice suing the new producers for copyright infringement.

As per media, the producers at Nariman Films said, "We have raised our objection through our advocates Digvijay Chopra and Iva Bansal."

Confirming that a legal notice has been sent to Excel Entertainment, Red Chillies Entertainment, Reliance Entertainment, Farhan Akhtar, Ritesh Sidhwani, Shah Rukh Khan and Baba Arts, Digvijay Chopra stated, "The remake rights were given only for the film Don - The Chase Begins Again, starring Shah Rukh Khan, by an agreement, which expired in 2009. Thereafter, they never renewed it or even take any prospective rights from Nariman films."

Bansal said, “Not only have they infringed upon the title registered by Nariman Films, i.e. Don and Don 2 - Return Of The King, which in this matter, is a second infringement. The first infringement is Don 2, made without taking the necessary rights as per the law.”

Bansal also explains that the title `Don 2` has been copyrighted in the name of Nariman Films in January 2005. "Reliance Entertainment has taken the distribution rights without any No Objection Certificate (NOC) from Nariman Films who hold the negatives of the original film Don. We shall also legally proceed with Paramount Films as we are informed that they are the overseas distributors," she maintained.

“We will be approaching the courts for stay on the release and promotions as well as confiscating all the Infringed Copies under the Copyright Act," said Chopra and Bansal. Ritesh Sidhwani of Excel Entertainment maintains, "Whatever we are doing is legal and their charges are false,” she added.
