"This is a very different film," Arshad said.
"Every film has it's own space, and the humour is absolutely funny. It's not political, it's fun... I had a great time doing this film," he added.
The film's producer Vashu Bhagnani said he hopes the audience enjoys watching the movie, which is directed by Ashish R Mohan and also stars Jackky Bhagnani and Lauren Gottlieb.
"Welcome To Karachi", said to be a political satire, is releasing on May 21.
