The 1970s and 1980s saw the rise of masala films, which were a blend of action, comedy, romance, and drama. Films like "Sholay" (1975), "Deewar" (1975), and "Tezaab" (1988) became blockbusters and redefined the Bollywood formula. These films were known for their catchy dialogues, memorable characters, and foot-tapping music.
