India's film industries
"Bollywood" is only one part of Indian cinema. India makes well over a thousand feature films a year, in more than twenty languages.

Each major language has its own film industry, with its own stars, studios and audiences, often nicknamed after Hollywood. Increasingly they share talent and release films in each other's languages.

"Pan-India" films
Since the mid-2010s, big-budget films are often shot in one language and released the same day in five or six. A Telugu or Kannada film can now be the biggest hit in Hindi-speaking states, and stars from all industries appear in each other's films. See South Indian films in Hindi.
