Dead in 1978. Motion pictures created in the 2000s, like 28 Days Later, the House of the Dead and Resident Evil films, and the Dawn of the Dead remake, have featured zombies that are more agile, vicious, intelligent, and stronger than the traditional zombie. These new type of zombies, the fast zombie or running zombie, have origins in video games, with Resident Evils running zombie dogs and especially The House of the Dead game's running human zombies. Spillover to television (2008–2015) The success of Shaun of the Dead led to more successful zombie comedies during the late 2000s to early 2010s, such as Zombieland (2009) and Cockneys vs Zombies (2012). By 2011, the Resident Evil film adaptations had also become the highest-grossing film series based on video games, after they grossed more than worldwide. In 2013, the AMC series The Walking Dead had the highest audience ratings in the United States for any show on broadcast or cable with an average of 5.6 million viewers in the 18- to 49-year-old demographic. The film World War Z became the highest-grossing zombie film, and one of the highest-grossing films of 2013. At the same time, starting from the mid-2000s, a new type of zombie film has been growing in popularity: the one in which zombies are portrayed as humanlike in appearance and behavior, retaining the personality traits they had in life, and becoming friends or even romantic partners for humans rather than a threat to humanity. Notable examples of human–zombie romance include the stop-motion animated movie Corpse Bride, live-action movies Warm Bodies, Camille, Life After Beth, Burying the Ex, and Nina Forever, and TV series Pushing Daisies and Babylon Fields. According to zombie scholar Scott Rogers, "what we are seeing in Pushing Daisies, Warm Bodies, and iZombie is in many ways the same transformation [of the zombies] that we have witnessed with vampires since the 1931 Dracula represented Dracula as essentially human—a significant departure from the monstrous representation in the 1922 film Nosferatu". Rogers also notes the accompanying visual transformation of the living dead: while the "traditional" zombies are marked by noticeable disfigurement and decomposition, the "romantic" zombies show little or no such traits. Return to decline (2015–present) In the late 2010s, zombie films began declining in popularity, with elevated horror films gradually taking their place, such as The Witch (2015), Get Out (2016), A Quiet Place (2018) and Hereditary (2018).
