And to clarify,"Bollywood" isn't an all-inclusive term for any film that comes out of India. There are other language regions in India too, like Tamil, Telugu, Malayalam, and Kannada, all of which have their own film industries. Bollywood is the most dominant one.
What makes Bollywood so popular? It knows how to tell a good story using all sorts of elements like extravagant songs, lush locations, and larger-than-life characters and stories, things that you usually don't see in other Asian film industries or in Hollywood. It often can’t fit into just one genre because it's an expert at genre-blending — drama and comedy, action and romance, you name it.
1) Not all Bollywood movies are three hours long and not all of them have song and dance. There are plenty of films that are more grounded and nuanced with no dances and no dream sequences and songs. Longer films usually have intervals in between so you can take a break. 2) Not every film is set in India and about Indian issues nor are they all traditional. Films are set and shot all over the world, take on a whole range of themes and topics, and there's everything from thrillers to action to horror to period films. There's a Bollywood movie for everyone.
Bollywood's favorite theme overall is love. Any kind of love — romantic, friendly, familial, etc. Emotion is at the heart of everything. No one can pull at your heartstrings better than Bollywood can!There are many wonderful actors in the industry but the name you have to know is Shahrukh Khan, one of the richest and most famous actors in the world. He's known as the King of Bollywood
