King of Bollywood is a biography by the film critic and journalist Anupama Chopra, chronicling the life and career of Shah Rukh Khan.

In the summer of 2003, she told him about the project; although his initial reaction was reluctant, Chopra tried to persuade him for around six months and Khan eventually changed his mind.

The book took three years to complete, with Chopra meeting Khan's close friends, school teachers, and collaborators in her writing process.

In 2000, along with the actress Juhi Chawla, Khan established the production company Dreamz Unlimited (later renamed as Red Chillies Entertainment in 2003), and its first release was Phir Bhi Dil Hai Hindustani (2000), which failed to garner wide attraction.

The idea of King of Bollywood arose when Anupama Chopra was interviewing Khan for a book—published in 2002—about the production and analysis of the 1995 film Dilwale Dulhania Le Jayenge.

"[4] In an interview to the entertainment portal Bollywood Hungama, she described the book as "an attempt to look at Hindi cinema and at India" through the actor's life and work.

[4][6] She revealed that in this process, she had conversations with the actor for around 30 hours, and would send SMSs and e-mails when he was shooting for the fantasy film Paheli (2005) in Jaipur.

[2] King of Bollywood marked Anupama Chopra's third book after Sholay: The Making of a Classic (2000) and Dilwale Dulhania Le Jayenge (2002).

Reviewing for Bollywood Hungama, Faridoon Shahryar called her writing "simple, informative, [and] engrossing" and found that she did not try too hard to grab attention from the book's readers.

[17] An Indo-Asian News Service critic wrote, "Anupama Chopra's ode to Shah Rukh's spellbinding stardom is far more intimate and compact, crisp and to the point, punctuated by bouts of humour occasionally directed at the star."

The critic appreciated her for not turning the book into a boring academic discussion as well as her ability to choice suitable words for describing the subject.

[18] In an article published in The Hindu, Savitha Gautam noted Chopra's writing was simple and "easy-to-read", stating that the readers would start to admire Khan when they read the book.
