Nasir Hussain

Filmistan was the breakaway studio from Bombay Talkies; it used mid-budget formula productions and sold on star value and music.

Sashadhar Mukherjee was a part of the breakaway team, and he gave Hussain Tumsa Nahin Dekha to direct.

Kapoor and Hussain made another hit, Dil Deke Dekho (1959), for Filmalaya, the breakaway group of Filmistan.

He was also in a long romantic relationship with her, but it ended because he was already a married man with two children, and Parekh didn't want to be labeled a homewrecker.

He made musical hits like Jab Pyar Kisi Se Hota Hai (1961), Phir Wohi Dil Laya Hoon (1963), Teesri Manzil (1966), Baharon Ke Sapne (1967), Pyar Ka Mausam (1969), Caravan (1971), Yaadon Ki Baraat (1973), and Hum Kisise Kum Naheen (1977).

Burman collaborated on Teesri Manzil, Baharon Ke Sapne, Pyar Ka Mausam, Caravan, Yaadon Ki Baraat and Hum Kisise Kum Naheen.

Vijay Anand directed the film, which starred Hussain's regular actors Shammi Kapoor and Asha Parekh.

Originally Dev Anand was signed for the film but due to differences with Hussain he opted out and Kapoor was cast.
