The star cast of 'Welcome To Karachi', including actor Arshad Warsi and Jackky Bhagnani, unveiled the trailer of their upcoming Bollywood movie. At the launch Arshad Warsi was really enthusiastic to promote his movie. Despite having a sore throat, he still managed to put up a good show and tried to answer all the questions by the media. However, the fun element created by Arshad was not really appreciated by the journalist at the launch.
