In 1971,Yash Chopra left brother director-producer B R Chopras home as well as production company to set up his own venture. During his last interaction with the media on his 80th birthday on September 27,he recalled: I had got married and I needed more money to take care of my family. When I told Bhai Saab he gave me his blessings and told me that from today I was on my own. With superhits like Dhool Ka Phool (1959),Waqt (1965) and Ittefaq (1969) already behind him,the industry took him seriously. Hence,his venture's first film,Daag starring Rajesh Khanna,Sharmila Tagore and Raakhee released in 1973 to houseful shows and established his banner,Yash Raj Films (YRF). Daag was one of the many cinematic love triangles that Chopra became synonymous with over the years. His track record in filmmaking while working with his brother also helped him rope in some of the best talents of the time. While the success of Kabhi Kabhie,Kaala Patthar and Silsila helped establish his banner,his iconic works like Deewaar and Trishul for Gulshan Rais Trimurti Films made him one of the top directors. The success of these two films played a key role in YRF becoming a powerful production house. Most actors were keen to work with it, says Ramesh Talwar,who assisted Chopra in the '70s. Chopras ability to adapt to the changing times and relate to the pulse of the audience made him the filmmaker of both the classes and the masses. Talwar recalls when the banner after the success of Silsila did not quite keep up the momentum. This,Chopra felt,was because he was making the same films everyone else was making. He decided to think out of the box and made Chandni. It was the starting point for the Yash Chopra brand: heroine-oriented stories,leading ladies clad in chiffon saris,excellent music,songs shot in Switzerland and unlimited romance. The movies that followed Lamhe,Darr,Dilwale Dulhania Le Jayenge,Dil Toh Pagal Hai,Mohabbatein and Veer Zaara mostly stuck to the same formula. However,while Chopra took his crew to foreign locales,he stuck to his roots,having Punjabi characters in almost all films. The banner became one of the most powerful in Indian cinematic history. The idea of the production house and studio grew in Chopras mind during the late 90s. He understood every aspect of filmmaking,from finance and production to marketing as well as direction and he brought these skills to his work, writes Rachel Dwyer,author of his biography. Over the 40 years of its existence,the banner has expanded into several things. Since 2006,this self-sufficient production house has had a high-tech sound studio,a music label,talent and marketing departments. Y Films is its youth-oriented production house. YRF also ventured into television. Some years ago,YRF felt the need to infuse new energy by introducing new directorial talent. Following the suggestion of Aditya,Yash Chopras elder son and current vice-chairman of YRF,the banner got new directors on board. Sanjay Gadhvi,who was one of the first outside directors to work for YRF along with Kunal Kohli,saw this as a strategic move. It was a planned move to ensure the growth of the banner and make it bigger, says Gadhvi. After all,it was the larger-than-life canvas that Chopra loved the most.
