"Anything that is cerebral or intelligent, they (people) think it's not my cup of 'coffee'," he said.
Addressing a gathering to announce the 17th Mumbai Film Festival earlier this week, the 43-year-old also said that he is "open to supporting all kinds of cinema", but independent filmmakers rarely knock at his doors.
"I'm open to supporting all kinds of cinema, but unfortunately some of them never come to me. They rather knock on Kiran Rao's door for these kinds of films," he said.
Karan's Dharma Productions had backed the internationally acclaimed independent film "The Lunchbox", which stars Irrfan Khan, Nimrat Kaur and Nawazuddin Siddiqui.
The 2013 film went globetrotting and was lauded at several international film extravaganzas in Cannes, Zurich, London and Toronto.
"Such rare endeavours are extremely few and far between," he opined.
Karan had recently shared that he was a huge movie buff irrespective of the various genres involved in them.
"It's a lesser known fact that I'm a huge lover of cinema. I don't have a life, I don't have a relationship and I don't have a spouse or children. I'm married to my company and I'm married to cinema," he added.
Karan's latest production venture "Shuddhi" will go on the floors after the release of "Brothers" in August.
