Give explanation for the following:
Why a number of Bombay films were about the lives of migrants.
Bombay became an attractive destination for people seeking jobs after the British administration replaced Surat with Bombay as its principal western port. The consequent increase in trade and industries led to a great influx of people. Thus, migrants were (and still are) an important facet of Bombay. Most of the people in the film industry were migrants themselves, and wanted to portray the plight of this class of people through films. Thus, a number of Bombay films were about the lives of migrants.
