Throughout the 1930s and 1940s, Mubarak continued to appear in a string of films which included Vasal ki Raat (1930), Noor Jahan (1931), Sati Mahananda (1933) and Maharani (1934).
The talkies brought newer opportunities for Mubarak when he learned the correct diction and fundamental tricks of voice control under the guidance of English actor and playwright Grant Anderson.
A slew of box office successes followed for Mubarak, who, by the late forties, has been a part of films like Kangan, Naya Sansar, Kismet, Tansen (in which he portrayed Emperor Akbar), Zaban, Manorma, Tadbir and Shabnam.
His stately visage and regal bearing made him an apt choice to play Gangadhar Rao in Sohrab Modi's costume drama Jhansi Ki Rani.
Raj Kapoor starrer Phir Subha Hogi, Main Nashe Mein Hoon, Dev Anand's Maya, Jab Pyar Kisi Se Hota Hai, Yash Chopra's Waqt, B. R. Chopra's Humraaz are some of his memorable films.
