With just a month to go for the release of Shah Rukh Khan-starrer ‘Zero’, the celeb and cinema star is set to plunge head on into the film’s promotions. From next week, SRK will reportedly begin shooting for stints on popular TV shows and gradually migrate to city tours. Shah Rukh will be joined by his two leading ladies, Anushka Sharma and Katrina Kaif, in the extensive marketing and promotional exercise. Directed by Aanand L Rai, ‘Zero’ features Shah Rukh Khan in a vertically challenged character Bauua Singh. While the film’s trailer received a good response on YouTube, the much awaited Bollywood flick is set to release soon. Salman Khan’s cameo song from ‘Zero’ will be released tomorrow, upping the excitement for the film. There are many other cameos in the film. R Madhavan, Jimmy Sheirgill, late actress Sridevi, Karisma Kapoor, Kajol and even Alia Bhatt will have special appearance in ‘Zero’, in which Shah Rukh plays a dwarf.
