He also starred in films with his own surname in the title such as "Mera Naam Johar", "Johar in Kashmir" and "Johar in Bombay", which is a testament both to his immense egotism, as well as his popularity with the common masses – for whom a movie with the Johar name was a guarantee of easy laughs, as well as subtle ironic or frankly sarcastic jibes at Indian customs, mores, superstitions and institutions. His film "Nasbandi" (Vasectomy) was a spoof on Prime Minister Indira Gandhi's failed policy of population control by coerced vasectomies during the period of Emergency and was "banned" when it was first released. In the plays written by him too, Johar attacks those in power. In a play on Bhutto, he writes about Pakistan's Prime Minister Zulfiqar Ali Bhutto as well as Gen Mohammed Zia-ul-Haq. Yash Chopra started his film career as an assistant director with I. S. Johar.
