"This is just a nomenclature, which is media created," Amitabh said at Solutions Summit, a day-long conclave to mark NDTV's 25th anniversary.
Shah Rukh agreed and said that those who are serious about the business need to think about much more.
"The true people who are really interested in the business of cinema, and talk about Rs.1000 crore. This Rs.100 crore and Rs.200 crore will keep changing. For a regular commercial film with a certain level of stardom, Rs.100 crore is just the base," he said.
In 2013, films like "Yeh Jawaani Hai Deewani", "Chennai Express", "Bhaag Milkh Bhaag", "Krrish 3" and "Goliyon Ki Raasleela Ram-Leela" have managed to surpass the Rs.100 crore mark.
Shah Rukh's "Chennai Express" minted Rs.216 crore.
