"I just love films. I write as if I am watching a film. Hence, in the head it feels like a film. It has the makings of a film and we are in talks with various Hollywood companies, but it's too early to say anything," Raj said at the launch of his book here Friday.
"There has been a lot of interest (regarding the film based on tghe book) and the day it happens, we will let you know," added Raj, who is married to Bollywood actress Shilpa Shetty.
Supporting her husband, Shilpa said: "I definitely see it becoming a film...a Hollywood film for sure. Raj likes to think big."
She says Raj is a bigger film buff than her, and she also stands true to his name 'Raj', which has been a popular choice of name for many of Shah Rukh Khan's romantic characters on screen.
"Let me tell you a secret. Raj is even more filmy than me. Raj is as filmy as you can get. He is the ideal Raj, like Raj from 'Dilwale Dulhania Le Jayenge'. For me, it is not surprising that it (book) is a little cinematic because that is how Raj thinks," Shilpa said.
"How Not To Make Money" is the story of three friends who live in London. Raj is a London-based businessman. He married Shilpa in 2009.
