It is not only the action and comedy genres that are doing well. Any film that is credible, entertaining and made with an honest effort will generate good business at the box office, like Kahaani and Vicky Donor. Content is king, and any film, whether action, comedy or romance that is made with a sincere effort, will never go out of style. No genre is ever out of style as long as it has good content.
Every genre will work as long as the script is strong. The audience likes to watch wholesome entertainers. So as long as the story is convincing, a film will work. An action film laced with humour is usually a winning combination. I guess Sholay is the best example.
I think action and comedy work all over the world. I am not saying other genres don’t work but since cinema is meant to entertain, action and comedy films are always appreciated. People can forget their worries and cares and laugh for three hours. Action is relatable because everyone wants to imagine themselves as heroes. The reason Salman Khan is a superstar is because he has struck a chord with the common man as Dharmendra did once upon a time. The audience expects the action hero to beat up 25 men all by himself.
Take Taare Zameen Par, for instance. It was a superb film and everyone loved it but it didn’t reach the 100-crore mark; whereas Singham did. Films like Singham encourage you to sit back and enjoy the ride. But, interestingly, other genres too are drawing good box office collections. Once upon a time, there was Amitabh Bachchan in films like Deewar and Zanjeer, and the same Bachchan did a film called Alaap, which flopped big time because that was a time when only masala films worked. But, for instance, if Ranbir Kapoor with his lover boy image does an action film, it may work because the industry is open to experimentation.
After Delhi Belly released, I read 41 scripts, among which 36 scripts were action and comedy. So producers want to follow those genres.
