Spider-Man is one of the most popular and commercially successful superheroes. As Marvel's flagship character and company mascot, he has appeared in countless forms of media, including several animated and live action television series, syndicated newspaper comic strips, and in a series of films. The character was first portrayed in live action by Danny Seagren in Spidey Super Stories, a The Electric Company skit which ran from 1974 to 1977. In films, Spider-Man has been portrayed by actors Tobey Maguire (2002–2007), Andrew Garfield (2012–2014), and Tom Holland (2016–present), who has portrayed the character in the Marvel Cinematic Universe since 2016. Reeve Carney starred as Spider-Man in the 2010 Broadway musical Spider-Man: Turn Off the Dark. Spider-Man has been well received as a superhero and comic book character, and he is often ranked as one of the most popular comic book characters of all time, alongside DC Comics' most famous superheroes, Batman, Superman, and Wonder Woman.
The practice may have originated in a Celtic festival, held on 31 October–1 November, to mark the beginning of winter. It was called Samhain in Ireland, Scotland and the Isle of Man, and Calan Gaeaf in Wales, Cornwall and Brittany. The festival is believed to have pre-Christian roots. After the Christianization of Ireland in the 5th century, some of these customs may have been retained in the Christian observance of All Hallows' Eve in that region—which continued to be called Samhain/Calan Gaeaf—blending the traditions of their ancestors with Christian ones. It was seen as a liminal time, when the spirits or fairies (the Aos Sí), and the souls of the dead, could more easily come into our world. It was believed that the Aos Sí needed to be propitiated to ensure that the people and their livestock survived the winter.
