"My character is that of an ex-navy man and he is accident prone. Somehow, he reaches Karachi without any documents or papers. So you can imagine what follows," the 46-year-old said here Friday at the 'mahurat' of the film.
"It is a comedy with political facts, but they have been shown in a very light way. There is no finger-pointing. It is a very light and fun film, but the facts are real and not fabricated," he added.
The film stars some Pakistani as well as American and Bangladeshi actors, and they will be shooting in London.
To be directed by Aashish R. Mohan, "Welcome To Karachi" also stars Irrfan Khan.
