Aamir Khan had earlier promised to clean theatre toilets to help promote his film releasing on May 29th, but this may now never happen.
According to One India, Khan has now threatening to withdraw his support, after a row with the producers.
A source said: "Aamir is irked because the producer is trying to fix a deal with certain multiplexes to release his film. Aamir had pledged support and promised to help only if the film released at single screens."
"The problem is, Big Pictures and the producer are co-producing the film Kal Kissne Dekha . Big Cinemas, the multiplex chain has now merged with Big Pictures.
"The two are now telling the producer that if he doesn't release the film at their multiplexes they won't allow him to release it elsewhere as well."
However, at a press conference held last month, both Shahrukh Khan and Aamir pledged all their support to the producers, and added that they would help to promote their films in single-screen theatres.
The producer then added: "Yes, I might release in single-screen theatres and also in standalone multiplexes. Aamir is planning to have a press conference along with other stars to outline marketing plans for the film."
Another source says, "Vashu is trying to garner support only for himself whereas Aamir will outline marketing plans for all releases in May. He'd been planning a press conference but yesterday he put it on hold."
An additional source told One India: "Aamir is very clear about one thing- either the producers take a united stand or he won't support the breakaway ones."
