if you think that a mere cameo can sell a movie then let me know the business Welcome to New York did.
and also tell me why was SRK's cameo in Tubelight teased?
let me tell you the difference, the teaser of Zero shows a good part of Salman's cameo, so people already know what it is and have seen a major part of it. SRK gave it to the audience to enjoy during eid.
and Tubelight merely teased SRK, so audience have to buy the ticket to see the actual cameo.
so tell me who is actually "selling" the movie on someone else's name, moron?
one more thing, kal Race 3 aa rahi hai uss pe focus kar, stop being obsessed with SRK.
