Most heroes did not want to sign this film due to Preity's role being bigger which Akshay Kumar confirmed in an interview. However Akshay was going through a very bad career phase so he agreed to do the film. Most who had seen his work vowed he would win the Best Actor Award. Preity Zinta would always say this in interviews. But Vaastav released the same year and Sanjay Dutt ended up winning.
