A film (or movie) is a visual art form that simulates experiences and communicates ideas through moving images, typically synchronized with sound since the 1930s. It works by rapidly projecting a series of individual frames, which the brain processes into a continuous motion through a phenomenon known as flicker fusion (or persistence of vision). As one of the most important art forms, cinema entertains, educates, and inspires audiences worldwide, and its universal visual language can transcend translation through dubbing or subtitles. The medium draws on earlier traditions like shadow puppetry and magic lanterns, with the core stroboscopic principle introduced in 1833 (phénakisticope) and later refined through the zoetrope (1866) and praxinoscope (1877). Photography breakthroughs, such as Eadweard Muybridge's 1878 sequential shots of a running horse in The Horse in Motion, alongside the chronophotography of Étienne-Jules Marey, paved the way for modern real-time motion capture. Ultimately, films are cultural artifacts that both reflect and actively influence the societies that create them.
