Hahaha...this is damn funny...but let me recollect something which I read in the magazine OPEN couple of issues back. This is an excerpt from an interview with Chandra Barot, the dude who directed the original DON. For more please follow the link below

"Q Who are the filmmakers you admire?
A I am an Aquarian, and Aquarians are supposed to be futuristic people. People say Don was 20 years ahead of its time, and I feel very happy. I appreciate Spielberg for the simple reason that not just cinema, he succeeded in creating a world which till then was just in the thoughts of people. Today, kids don’t have to visualise what dinosaurs are. They can see it there in Jurassic Park. He made a film called Duel, with only two characters. It was unbelievable how he sustained the film with only two people, a car and a truck.
I admire James Cameron too. Once we were sitting at an awards function, and Raaj Kumar’s son Puru came and said, “Sir, tell me something. If I come to you with a script where, in a ship a passenger from the third-class falls in love with a lady from the first class and the ship sinks, would you make a film on it?”
What do you say Kaftan? what to make of this? Did Puru approach Cameron or Chandra?
But also i must say the resemblance is uncanny, kaka really was way ahead of his times
