Akshay Kumar's "Rustom" has a serious premise; it is loosely based on the infamous Nanavati case of 1959. Because the subject isn't something that can be made light of, the actor has decided to promote it on "The Kapil Sharma Show" ("TKSS") and not "Comedy Nights Bachao" ("CNB").

"CNB," which is Krushna Abhishek's show, thrives on insults and humiliating jibes, but it's not the same with "TKSS," which is mild with a flexible script.

CNB is a humour-centric show and 'Rustom,' the film he is promoting, has a very serious subject. He thinks it's the wrong fit for a film like this and promoting it on that show, won't help the film. Rustom is a serious crime-drama and Akshay is very clear how he wants to promote it," an insider told DNA

The promotions of "Rustom" on Kapil Sharma's comedy show will not be all about "laughs and gags." The episode will be shot keeping in mind the tone of the film and is expected to have the armed forces as its theme. The script is said to have been tweaked to suit the feel of the crime-thriller.

So the reason for Akshay's unwillingness to take "Rustom" to "CNB" is apparently different from what was being said in the last few days. Several insiders claimed that his experience from the last time he had visited Krushna's show has made him reconsider his options.

Meanwhile, the daily's source confirmed there's no enmity between the superstar and the funnyman, adding that they share a great rapport and have worked together in films.

"Rustom" arrives in theatres on Aug. 12 and stars Ileana D'Cruz, Esha Gupta and Arjan Bajwa in key roles.
