Tamil cinema later had a profound effect on other filmmaking industries of India, establishing Chennai as a secondary hub for Bollywood, other regional film industries in South India, as well as Sri Lankan cinema. In its modern era, Tamil films from Chennai have been distributed to various overseas theaters in Singapore, Sri Lanka, South Africa, Malaysia, Japan, Oceania, the Middle East, Western Europe, and North America.
