Younger sister of actress Salma Mumtaz, Shammi belonged to very poor family. Shammi (Shimmi) was introduced by director Munshi in the Punjabi film of the same name Shammi (1950), opposite Santosh Kumar, Ajmal and Shola. At that time Pakistani film industry was at its nascent stage and was generally unable to compete with the technically superior Indian films. Even then, Shammi did average business because if its soulful music composed by Master Inayat Hussain. Shammi was produced by Malaika Pukhraj and her husband Syed Shabbir Hussain Shah. Malaika Pukhraj sang an Urdu song in this film “Kia sunain majboor zindagi ka afsana”. Other popular songs from this film were “Suhe chorey walie” by Inayat Husain Bhatti and “Meri Akh Mustani Pharhke” by Iqbal Begum.
Later she appeared in a few more films including Beqarar, Ilzam, Mehbooba, Tadap, Roohi, Khizan Kai Baad, Sohni and Pawan. Of these special mention must be made of Roohi, which became the first film banned by the Film Censor Board of Pakistan. The government said the film generated ‘class hatred’, and portrayed a ‘rich married woman having an affair with a young, unmarried man’.
Shammi married her co-star of several films Sudhir and bid adieu to her film career to become a devoted house wife. However, she did appear in two films Sahil (1960) and Baghawat (1963) after getting married, both produced by her husband Sudhir.
