Karan Johar is known for his lavish emotional dramas, but when it came to remaking his father's action film "Agneepath", he gave full rein to director Karan Malhotra. Versatility, he admits, is not his forte, and he can only do human emotional dramas.

"I am not a versatile filmmaker, I can do only one kind of film. I think, I can do human emotional dramas, but I don't think I can pull off action films, thrillers or do something which is completely edgy," Johar told an Oye 104.8 FM radio host.

"Like I can't make films like 'Gangs of Wasseypur', 'Udaan', 'Taare Zameen Par', they are all good films. That's my biggest limitation," he added.

However, the 40-year-old loves his work, and feels his love for movies helps him avoid a feeling of loneliness due to his bachelor status.

"My mother is the most happy that I am not married, as she does not need to share her jewellery with anyone," quipped the filmmaker when asked "Don't you want to get married?"

But on a serious note, he added: "I just want to make films... My office has become my family. People who work in my office have become my world. I really don't feel the need for anyone."

He also admits that he is not as expressive as people think he is.

"The truth is that I hold back! I don't express my feelings to anyone! When I am hurt, I keep it to myself. Then after two to three years, it comes out in some other situation," he said.
