A "thrilled" Farhan on Wednesday tweeted that the upcoming film will be based on a boxer.
"Thrilled to share that six years after Bhaag Milkha Bhaag, Rakeysh Omprakash Mehra and I are reuniting to create 'Toofan', a heartfelt story of a boxer. Hope for your best wishes as we embark on this new journey. Love."
Other details of the films are still under wraps.
The film will be jointly produced by Excel Movies and ROMP Pictures.
