Director Nikhil Advani says his next movie "Patiala House", about cross-generation cultural assimilation among the Sikh community in Britain, is partially based on the infamous Southall racial riots of 1979 and is like reopening old wounds.

Advani shot a few scenes in the much-revered Southall Gurdwara of London. Cameras are not usually allowed there, but once the Southall Gurdwara committees heard the idea behind the film and that Rishi Kapoor and Akshay Kumar would feature in it, they were all for the project.
