The Pakistan government has restrained its cable operators from screening promos and reviews of the upcoming Yash Raj Films’ Salman Khan-starrer <em>Ek Tha Tiger</em>, saying that the film is aimed at tarnishing the image of the ISI. A letter issued by the Pakistan Electronic Media Regulatory Authority (PERMA), country's media regulatory watchdog, to all satellite TV channels and cable networks last week said <em>Ek Tha Tiger</em>, set for world release on 15 August, is “reportedly based on the activities of ISI and RAW.”
