Once, a producer went to court to get a decree that Kumar must follow the director's orders. As a consequence, he obeyed the director to the letter. He refused to alight from his car until the director ordered him to do so. After filming a car scene in Bombay, Kumar drove until he reached Khandala because the director forgot to say "Cut". In the 1960s, a financier named Kalidas Batvabbal, who was disgusted with Kumar's alleged lack of cooperation during the shooting of "Half Ticket", reported to the income tax authorities, who raided his house. Later, Kumar invited Batvabbal to his home, asked him to enter a cupboard for a chat and locked him inside. He unlocked Batvabbal after two hours and told him, "Don't ever come to my house again".
