The culture of West Bengal is an Indian culture which has its roots in Bengali literature, music, fine arts, drama and cinema. Different geographic regions of West Bengal have subtle as well as more pronounced variations between each other, with Darjeeling Himalayan hill region and Duars showing particularly different socio-cultural aspects. West Bengal's capital Kolkata—as the former capital of India—was the birthplace of modern Indian literary and artistic thought, and is referred to as the "cultural [or literary] capital of India". The presence of paras, which are cluster of neighbourhoods that possess a strong sense of community, is characteristic of West Bengal. Typically, each para has its own community club and, on occasion, a playing field. Residents engage in addas, or leisurely chats, that often take the form of freestyle intellectual conversation. However, with the growth of apartments, expansion of neighbourhoods and rapid urbanization, this culture is on decline. Literature The Bengali language boasts a rich literary heritage, shared with neighbouring Bangladesh. West Bengal has a long tradition in folk literature, evidenced by the Charyapada, Mangalkavya, Shreekrishna Kirtana, Thakurmar Jhuli, and stories related to Gopal Bhar. In the nineteenth and twentieth century, Bengali literature was modernized in the works of authors such as Bankim Chandra Chattopadhyay, Michael Madhusudan Dutt, Rabindranath Tagore, Kazi Nazrul Islam, and Sharat Chandra Chattopadhyay. Coupled with social reforms led by Ram Mohan Roy, Swami Vivekananda, and others, this constituted a major part of the Bengal Renaissance. The middle and latter parts of the 20th century witnessed the arrival of post-modernism, as well as literary movements such as those espoused by the Kallol movement, hungryalists and the little magazines. Theater and films Among other types of theater, West Bengal has a tradition of folk drama known as jatra. Kolkata is the home of the Bengali cinema industry, dubbed "Tollywood" for Tollygunj, where most of the state's film studios are located. Its long tradition of art films includes globally acclaimed film directors such as Academy Award-winning director Satyajit Ray, Ritwik Ghatak, Mrinal Sen, Tapan Sinha, and contemporary directors such as Aparna Sen, Buddhadeb Dasgupta, Goutam Ghose, Koushik Ganguly, Rituparno Ghosh, Anjan Dutt, Kamaleswar Mukherjee, Sandip Ray. Uttam Kumar was the most popular lead actor for decades, and his romantic pairing with actress Suchitra Sen in films attained legendary status. Soumitra Chatterjee, who acted in many Satyajit Ray-films, and Prosenjit Chatterjee are among other popular lead male actors. ,
