The producer and director has previously updated his father Yash Johar's hit Agneepath.
He told The Times of India: "I am okay with remakes. If you can give your own edge and slant, then why not? I think there is a dearth of writers, but I don't think that's why people make remakes.
"It's also your sense of creativity and what you want to do with it. Remaking it in exactly the same way is no fun. Revisiting it in a certain way and adjusting it to the modern times always makes it interesting."
He added: "I wanted to pay a tribute to a film which my father had produced and Mukul [S Anand] had directed fantastically. I wanted to make sure that we make it in a different way, which I believe in."
Johar recently denied that his romantic comedies have a "formula".
He was in talks to sell the Tamil-language and Telegu-language rights to Agneepath earlier this year.
