Mansoor Khan's 1988 directorial debut 'Qayamat Se Qayamat Tak', starring Aamir Khan as Raj and Juhi Chawla as Rashmi, was a pathbreaking film not only because it was a much-needed young love story in the 1980s era of hollow action entertainers, but also because of its unexpected ending.

Both Raj and Rashmi, after eloping to the jungle away from their disapproving families, are killed for their rebellion in the end.

It's a lesser-known fact that Mansoor's father and legendary filmmaker Nasir Hussain insisted on a happy ending for the film. "While we were writing, he wanted a happy ending. So, he told Mansoor to shoot both the endings - happy and sad - and then they'd decide in the edit which one works better," Aamir revealed recently.

Mansoor revealed that in the alternate happy ending, instead of Juhi's character getting shot and then tumbling down the rocks to death, it was Goga Kapoor's character, Randhir Singh, who met that fate. "In the happy ending, the killer points the gun at Juhi when she's screaming, 'Raj! Raj!'. And then he hears somebody scream, 'Rashmi! Rashmi!' That was Goga Kapoor. This guy is a greater threat, so he shoots Goga Kapoor," said Mansoor.

The filmmaker recalled how none of the actors could take that ending seriously as they kept cracking up while filming the final mid-closeup shot of Goga's character breathing his last. "He has blood coming out. For the mid-close-up shot, everybody came around to see him. But before I can call action, one of the actors starts laughing. Not the spot boy, one of the actors! It happened two or three times. Then Goga said, 'Saalon main mar raha hu, tum has rahe ho!' (I'm dying here and you guys just keep laughing!). That was the proof that it wasn't working," added Mansoor.
