Prithvi Raj Kapoor's first film was a silent film called 'Cinema Girl'29' opposite Ermaline. Unfortunately, this film did not fare well and Prithvi Raj was left stranded. He had his three sons to look after and so opted for miniscule roles. He was one of the extras in 'Alam Ara' (1931), India's first talkie. He slowly graduated to doing strong roles of a king. Most of his films were 'Sapera', 'President', 'Duasman', 'Vidyapati' and 'Sikander'. But one film for which he is most remembered is 'Mughal-e-Azam' where he played the role of Emperor Akbar.
Unfortunately, his grandson Randhir's first film turned out to be the last for him. During the making of 'Kal Aaj Aur Kal', Prithvi Raj met his death. But not before he had achieved much as an actor and filmmaker. He even established a theatre called Prithvi Theatre.
