I have watched some Bollywood style movies before and loved the visual style, the music, and some of the hidden messages but I did have some questions.
Is it typical to have English mixed into the dialogue or was that part of a hidden message as well?
It's very common in Indian movies for some of the language to be English. It's part of the history and culture of India, after all.
It's like Spanglish. I found this wiki article about "Hinglish": https://en.wikipedia.org/wiki/Hinglish
Here's an article that talks about Hinglish and Hinglish in Bollywood: http://www.firstpost.com/ideas/does-hinglish-democratize-english-33714.html
I don't know, when I went to India I spent over half the time in small villages, where almost no one spoke English, and I don't remember hearing a bit of Hinglish. So perhaps it's more common in big cities.
