The veteran director reportedly plans to celebrate the event on September 27 with a party, where he will reveal the first promo of the eagerly anticipated film along with its title, Mid Day reports.
"Yashji will be launching the theatrical and the title of his much talked-about film. His banner Yash Raj Films has also entered its 40th year. His first film Daag released in 1973," a source said.
"Although Yash Chopra does not believe in throwing parties and stuff, this time around they are planning to have a lavish party.
"After the current Ladakh schedule, the promo will be ready and Aditya Chopra is taking special care to make this film the biggest film of Yashji's career.
"Although the name of the film has been finalised as Yeh Kahan Aa Gaye Hum, Yashji, Aditya Chopra and SRK are still considering other names."
An official spokesperson from the production house commented on the news, saying: "It will be a great day for us to launch the promo as it fits in perfectly with our promotional timeline. However, since the film is still being shot, we aren't able to confirm this right now."
Chopra, who returns to direction after an absence of eight years, will also be marking 50 years as a filmmaker.
