Julia Roberts character was much lower status than Richard gere's character.
The relationship between the two started off business-like: he was paying for her services. He was relatively heartless in the beginning. He only needs her services whilst he completes a deal.
They stay in the same hotel suite. She has no clothes and he buys her some transforming her into a swan.
She also learns how to behave and carry herself in preparation for an important dinner.
Throughout the process, she also changes him - makes him more human!
I know there are lot of differences as well (Khushi is definitely not going to sleep with arnav and she is no call-girl) but I think the gist is the same for this Nainital track.
What do you think?
