The film opens with two child actors playing the character of the older brother (Prashant) and the younger sister (Janice) separated by just a few years apart. As the characters grow into adults, there is an obvious but a visually significant age gap between Prashant and Janice. Dev Anand (who plays the adult Prashant) was 47 years old whilst Zeenat Aman (who plays the adult Janice) was only 20 during the film's production. This meant that the resulting age gap between the two actors increased from a few years to 27 years apart.
