It is said that Aishwarya Bachchan was supposed to be part of Dostana but she decided to drop out on her own. When asked she said that it was her decision drop out because she felt that the film was actually based on the chemistry and the rapport that John Abraham and Abhishek Bachchan share. It's not about her love story. She personally felt that if she would be in the film then the entire focus would be on her and Abhishek and the main story of the film would be sidelined. The viewers would start expecting a love story between them and the fun space and chemistry between Abhishek John would be neglected.
She also said that as the movie was supposed to be filmed back then and be her first release after marriage she did not want the viewers to start assuming things. They were seen together in Sarkar Raj but in a serious role but Dostana being a light and fun-filled film, she did not want to spoil the fun so she decided to walk out.
When asked about the kissing scene between John and Abhishekh all she had to say was finally all that mattered was if the viewers enjoyed the film or not.
