In 2001 Rahul Rawail made Kuch Khatti Kuch Meethi which also was inspired from Parent Trap and starred Rishi Kapoor.
Remake of The Parent Trap. The Parent Trap was earlier made as Do Kaliyan with Neetu Singh then as Pyaar Ke Do Pal with Mithun Chakraborthy and Jaya Pradha.
Rishi Kapoor was doing Umesh Mehra movie Pyar Ke Do Pal. After a argument, they chucked Rishi out of the film. To take revenge, Rishi took the films story and told Anil Ganguly to make the film fast. That is how Pyar Ke Kaabil was created .
The producers were in a rush to release the film before Pyar Ke Do Pal. This was due to both being a remake of Do Kaliyan .This is when Padmini told the producers she was going abroad for a holiday. She was going to Belgium. The producer panicked and decided to shift the film unit to Beligium to shoot Padmini's remaining scenes. That is when the accountant told the producer it would cost him 3 times more if he went to Beligium rather than wait for Padmini. Cooler minds prevailed and the producer waited for Padmini to return. But in the process the film did get delayed and Pyar Ke Do Pal released first.
At the beginning of the movie the light suit which Rishi Kapoor wears is similar to the one Amitabh Bachchan wore in Yaarana during the song Sara Zamaana. Coincidentally in the movie when one of the twin daughter's sends the other a telegram it is mentioned in the message that Amitabh Bachchan is coming into town
