The movie also explores Dutt's personal life, including his relationships with actresses like Tina Ambani (played by Dia Mirza) and Manisha Koirala (played by Boman Irani's daughter, Gracia). The film humanizes Dutt, presenting him as a flawed individual struggling with addiction and personal demons.

Upon its release, "Sanju" received widespread critical acclaim, with many praising Kapoor's performance and Hirani's direction. The film was a commercial success, grossing over ₹ 400 crores worldwide.

However, the film's central plot revolves around Dutt's association with gangsters like Abu Salem (played by Sachin Khetre) and Chhota Shakeel (played by Randeep Hooda), and his subsequent arrest by the Mumbai Police in 1993. The film's portrayal of Dutt's involvement with the underworld and his trial raises questions about the blurred lines between crime and glamour in Bollywood.

The film's technical aspects are noteworthy, with a captivating score by Tanishk Bagchi, and impressive cinematography by Aseem Ahluwalia. Ranbir Kapoor's performance as Sanjay Dutt is particularly laudable, capturing the actor's mannerisms and vulnerabilities.
