"I term such films (movies entering the Rs.100-crore club) as hit-and-run cases. With promotional techniques, the hype created around the film is such that the film works till Monday," the actor said at a session of Agenda Aaj Tak in the national capital.
Ajay emphasised that entry in the Rs.100-crore club doesn't guarantee success.
"Nowadays, films are made on big budgets. So, the entry in the club doesn't mean success. In fact, actors don't get any benefit from such movies. Producers as well are not big gainers due to the budget. Hence, the success of the film depends on the profit as compared to its budget," said Ajay, who looked sporty in a black leather jacket.
Promotional activities are now a common thing, with actors going a step ahead and trying something new for the movie's publicity.
Ajay says a lot has changed in Bollywood now and he puts himself among the lucky lot of Bollywood who have seen the transition.
"A lot of things were not there back then, like media, make-up vans, mobile phones. During outdoor shoots, we used to stand in lines and wait for our chance to make a call.
"As the media was not there, we had no way to promote our films. There was a programme on Doordarshan, where on one serial our song was played and that was promotion. I think the change is good but the best thing is that we have seen the transition," he said.
The actor also felt that the charity one does should not be used for promotion.
"I am associated with a number of associations for charity and people know they can depend on me when needed, but I don't believe in speaking about my work towards the society," he said.
