Why so many Bollywood movies about Punjabi culture?

Just about every other movie has a Punjabi connection. The most recent Sharukh Khan movie Rub Ne Banadi Jori is an example. Another example is the upcoming Shahid Kapoor movie whose name I don’t remember, and Love Aaj Kal.

Does Punjabi culture really have such a huge impact influence on general Indian culture? What relation could someone from Mumbai, Kerala or Bihar have to Punjabi culture? Are there really that many Sikhs that every movie must have one?

If Pakistani movies did this it’s understandable due to Punjabi being the most spoken language, most populated province and a lot of actors and singers coming from Lahore. But just seems a bit odd that Bollywood movies show so much Punjabi culture.

Not dissing on it or saying anything bad, just wondering about this Bollywood and Punjabi culture connection. I don’t recall a lot of Bollywood movies from the 80’s doing this.

not just people from punjab but people in delhi also speak punjabi, just like people in lahore.

Too many Punjabis in movie industry. They have created movies where the
hero is always a Chopra or a Malhotra very handsome and dashing while all other characters are buffons like miserly Marwadi, foolish Gujarati, corrupt
Marathi policeman, Marathi kaamwali bai, comedian South Indian.

Hindi movies are far from realistic. If you want to watch good cinema watch some of the regional movies. Kannada, Bengali, Malayalam have some grea movies. Over the last few year Marathi movies are top of the line.
