The film is reportedly about two brothers (to be played by Shah Rukh Khan and Ranbir Kapoor) who fall in love with the same girl.

If anyone can pull off a casting coup, it’s Karan Johar. Whether it is getting superstars to do cameos in Dharma films or guests on his Koffee With Karan couch, the Ae Dil Hai Mushkil director leaves no stone unturned to make sure he gets the best actors. Now, if a report in DNA is to be believed, KJo is planning to rope in either Katrina Kaif or Deepika Padukone for his next. What is so special about that, you ask?  Well, the film in question is a love triangle with Ranbir Kapoor and Shah Rukh Khan as the male leads.
While Katrina Kaif is quite pally with her ex Salman Khan, the same cannot be said about her equation with former boyfriend Ranbir Kapoor. In fact, it was being reported that there was a lot of awkwardness between the two of them on the sets of Jagga Jasoos (which began filming in 2014, when the couple was still together). On the other hand, Deepika has continued to remain great friends with Ranbir after their break-up, and their chemistry was the talking point in Yeh Jawaani Hai Deewani and Tamasha.

Shah Rukh Khan has also had great success with films where he was paired with Deepika (Om Shanti Om, Chennai Express, Happy New Year). SRK was paired with Katrina in Jab Tak Hai Jaan, which also became a hit.   It remains to be seen who will be the leading lady in the film, which is a reportedly about two brothers who fall in love with the same girl.
