Bollywood superstar Shah Rukh Khan's Red Chillies Entertainment is collaborating with Karan Johar's Dharma Productions and BR Studios for the remake of "Ittefaq." The recent buzz is Sidharth Malhotra and Sonakshi Sinha will be roped in to recreate the magic of Rajesh Khanna's 1969 release.

"Yes, it is true that Sonakshi and Sidharth will feature as the lead in the 'Ittefaq' remake. Currently the film is in the prep stage and narration will commence shortly and is expected to go on floors later this year," Bollywood Hungama quoted a source as saying.

The original "Ittefaq" had been directed by Yash Chopra, and was his first film with Rajesh Khanna, who was a big star at that point. The remake will be helmed by Abhay Chopra (grandson of BR Chopra and son of Ravi Chopra) and will most likely go on floors this year.

The film, "Ittefaq," is a murder-mystery, in which Dilip Roy (Rajesh), a painter, is accused of murdering his wife and later sent to an asylum, where he seeks professional help. It was reportedly a semi-hit at the box office and was one of the few films of the time that didn't have any song.

It has been reported that the climax of the remake will be changed. Interestingly, the Yash Chopra directorial was also a remake of a 1965 film named "Signpost to Murder," starring Joanne Woodward, Stuart Whitman and Edward Mulhare.

Meanwhile, Sonakshi and Sidharth are busy with their respective projects. After "Kapoor and Sons," Sidharth will be seen opposite Katrina Kaif in "Baar Baar Dekho." Also, the actor is going through several scripts.

Sonakshi, on the other hand, is shooting for Abhinay Deo's "Force 2" opposite John Abraham. She will also be seen in A.R. Murugadoss' "Akira," which is set to be released on Sep. 23. Additionally, it has been reported that the actress will star in a film based on Saba Imtiaz's popular novel "Karachi, You're Killing Me!" in which she will play a journalist named Noor.
