By the late 1950s, it was clear that the era of the travelling theatre had been irreversibly supplanted by the cinema and it was no longer financially feasible for a troupe of up to 80 people to travel the country for four to six months at a time along with their props and equipment and living in hotels and campsites. The financial returns, through ticket sales and the rapidly diminishing "largesse" of patrons from the erstwhile princely class of India, was not enough to support such an effort. Many of the fine actors and technicians that Prithvi Theatres nurtured had found their way to the movies. Indeed, this was the case with all of Prithviraj's own sons. As Kapoor progressed into his 50s, he gradually ceased theatre activities and accepted occasional offers from film-makers, including his own sons. He appeared with his son Raj in the 1951 film "Awara" as a stern judge who had thrown his own wife out of his house. Later, under his son, Shashi Kapoor, and daughter in law Jennifer Kendal, Prithvi Theatre merged with the Indian Shakespeare theatre company, "Shakespeareana", and the company got a permanent home, with the inauguration of the Prithvi Theatre in Mumbai on 5 November 1978.
