Khan was filming a romantic scene for the film in Kashmir, where Tiger and Kriti were made to sit on a 10-feet high swing. While shooting the scene, they slipped and fell off the swing on the ice-covered ground, injuring themselves.
The actors suffered minor injuries, but were all eager to shoot the scene again.
Khan said that it is extremely brave and commendable that both Kriti and Tiger were up on their feet and wanted to shoot. He was concerned they might have to call it a day.
"The temperature was minus nine that day and both of them fell straight into the ice below, making the pain unbearable, especially since they were in minimum costumes from the film, as opposed to the crew, that was heavily layered for snow," Khan said in a statement.
"Heropanti" will hit the theatres May 16.
