"I would not act and produce an adult comedy film. But that doesn't mean I have a problem with it. I am not comfortable doing adult comedies.. it is not in my DNA. That's not my space," John told PTI in an interview here.
"Comedy in general is beautiful. To make people laugh is lovely. It feels great when people laugh and go home. I want to make people happy. I want to do something that is harmless," he said.
At a time when when Bollywood is churning out quite a few adult comedies and they are doing well at the box office, the "Madras Cafe" actor feels there is a space in the market for everything.
"There is nothing wrong with it. There is a market for everything and everybody has the right to make what they want. And everyone has the right to see what they want to see," the 42-year-old actor said.
John emphasised that guidelines should be followed while watching adult comedy films. "If an adult comedy is made, it gets an 'adult certification'. So, there are guidelines according to which youngsters are not suppose to see it," he said.
John will be next seen in Anees Bazmee's comedy "Welcome Back", the sequel of 2007 hit "Welcome". The multi-starrer film releases tomorrow.
