Is Bollywood really bigger than Hollywood?

A big NO. Bollywood always copied Hollywood films and even posters too.

Until they stop following Hollywood and follow their own cultural, then they'll be bigger than anyone.

Hollywood have lot of educated and famous directors and producers (example - James Cameron) and lot of foreigners people from different countries, takes part in Hollywood (USA) industry, not Bollywood. Example - Emma Watson from England, Andy Serkis from England, Chris Hemsworth from Australia, Gary Oldman from England and many more.

Because Hollywood still have high quality of making films, example Avatar, The Avengers - infinity war, Black Panther, Dawn of the Planet of the Apes etc.

Bollywood is still struggling a lot in this position, where Hollywood already reached long time ago. So, those people who said that Bollywood is bigger than Hollywood, then I'm 100% sure that they never watched Hollywood films. Bollywood really can't beat Hollywood at all, until they follow their own cultural and rules, instead of copying Hollywood.
