Ranbir Kapoor had suggested the title of the film Jab Harry Met Sejal.
Shahrukh Khan revealed that he was signed only after Ranbir Kapoor declined the lead role.

The film was initially conceived about a man trying to commit suicide. However, after Shahrukh Khan met Imtiyaz Ali, the former suggested to revitalize the story by making it a more jolly film.
The film underwent a lot of name changes throughout its production phase from The Ring to Rahnuma to Raula until it was finalized with Jab Harry Met Sejal.
