Acting star Mohanlal was reportedly going to be associated with the project, but it didn't work out.
"Mohanlal is not in the film, unfortunately. We didn't have a strong enough character for a man of his stature to be in. But I can assure you that the beauty of 'Madras Cafe' is the casting. Even with 'Vicky Donor', we got so many new faces which people had not seen before but it clicked well," John told IANS.
Describing the movie, John said: "I am sure people down south will appreciate what we have done. It's a story about an agent and the story is told from his point of view. We researched for it for six years and it has honest content. The 30-plus audience will relate to this film immediately."
The film releases Aug 23.
