"I respect Gandhiji a lot and totally believe in his ideology of non-violence. I'm a very non-violent man, " John told reporters here.
The actor was present at a bookstore to distribute the Mahatma's autobiography as a promotional activity for his forthcoming film "Jhootha Hi Sahi" where he will essay the role of the owner of a book store.
"I own a book store in the film so on a day like today, which is Mahatma Gandhi's birthday, we are here to sell books to the customers, " said John.
Director Abbas Tyrewala and John's co-star in the film Raghu were also present at the event.
John, who was dressed in his geek look complete with broad-rimmed glasses, also revealed that his girlfriend and actress Bipasha Basu is also quite happy with his look in the film.
"When Bipasha saw my look in the film, she said that if there is any director who has managed to break me down physically and in terms of a character on screen, its Abbas.
"She completely loves my look. She said that this is the film I want to watch because its very unique, very fresh, " he added.
The film, made under the Saregama banner and slated to hit screens Oct 15, is about a suicidal woman whose final call mistakenly connects her to a man who gives her something to live for.
