as the many zombie films it inspired, such as The Return of the Living Dead (1985) and Zombi 2 (1979), are usually hungry for human flesh, although Return of the Living Dead introduced the popular concept of zombies eating human brains. There has been an evolution in the zombie archetype from supernatural to scientific themes. I Am Legend and Night of the Living Dead began the shift away from Haitian dark magic, though did not give scientific explanations for zombie origins. A more decisive shift towards scientific themes came with the Resident Evil video game series in the late 1990s, which gave more realistic scientific explanations for zombie origins while drawing on modern science and technology, such as biological weaponry, genetic manipulation and parasitic symbiosis. This became the standard approach for explaining zombie origins in popular fiction that followed Resident Evil. There has also been shift towards an action approach, which has led to another evolution of the zombie archietype, the "fast zombie" or running zombie. In contrast to Romero's classic slow zombies, "fast zombies" can run, are more aggressive and are often more intelligent. This type of zombie has origins in 1990s Japanese horror video games. In 1996, Capcom's survival horror video game Resident Evil featured zombie dogs that run towards the player. Later the same year, Sega's arcade shooter The House of the Dead introduced running human zombies, who run towards the player and can also jump and swim. The running human zombies introduced in The House of the Dead video games became the basis for the "fast zombies" that became popular in zombie films during the early 21st century, starting with 28 Days Later (2002), the Resident Evil and House of the Dead films and the 2004 Dawn of the Dead remake. These films also adopted an action approach to the zombie concept, which was also influenced by the Resident Evil and House of the Dead video games. Film and television Films featuring zombies have been a part of cinema since the 1930s. White Zombie (directed by Victor Halperin in 1932) and I Walked with a Zombie (directed by Jacques Tourneur; 1943) were early examples. With George A. Romero's Night of the Living Dead (1968), the zombie trope began to be increasingly linked to consumerism and consumer culture. Today, zombie films are released with such regularity (at least 55 films were released in 2014 alone) that they
