However, Johar was in no mood to let them pass and took to sarcasm to give fitting replies to these comments.
A Twitter user took a dig at Johar for favouring close friends and family, to which Johar said: "You must stop immediately or the world will come to a drastic end!"
A second troll, who took on the ace director for his film 'Takht', was not spared either.
He wrote, "Ma'm...your clever coinage is original and has a dash of humour but nothing can match your beautiful DP image! Hand on chin and looking at an undisclosed location...."
"Hello uninformed person! You cannot promote something that is already a big hit!" Karan responded.
After directing the Ranbir Kapoor-Anushka Sharma-Aishwarya Rai Bachchan-starrer 'Ae Dil Hai Mushkil', Karan will be donning the director's hat for 'Takht' after two years.
The flick, starring Ranveer Singh, Kareena Kapoor Khan, Alia Bhatt, Janhvi Kapoor, Anil Kapoor, Vicky Kaushal and Bhumi Pednekar, will hit the theatres in 2020.
