A sequel named Gyrah was to be made after Dus, but it was shelved.
While the cast were shooting in Canada, a newspaper published an article accusing Sanjay Dutt of being a terrorist. Whether the article was a genuine claim or was done to promote circulation is not known, but it distressed Dutt so much that he canceled everything and flew back home, losing five days' work.
Dus Bahane track became very popular.
A background dancer, Jhanvi Kapoor, claimed she was married to Abhishek Bachchan. On the day of his wedding she slashed her wrist in front of his house. Years later there was speculation that Jhanvi, who has since become a godly woman, would be in Big Boss 11.
The whole plot where Pankaj Kapoor pretends to be a mere associate of the main antagonist Jamwal and make a fool of the cops is lifted from The Usual Suspects (1995). Chocolate released in the same year was a scene to scene copy from The Usual Suspects.
