The creature, which burst out of John Hurt’s chest in the 1979 Alien film before appearing in sequels, has been named the most frightening creation from film history in the poll for the Radio Times.
The skeleton army from Jason And The Argonauts (1963) took second place, and The Thing from the 1982 film of the same name was third.
Only two relatively recent creations — phantom species the dementors from the Harry Potter movies, and Pale Man, which feeds on children and fairies, from Pan’s Labyrinth (2006) make the top 10.
Nightmare On Elm Street’s serial killer Freddy Krueger (1984) and the great white shark from Steven Spielberg’s Jaws (1975) complete the top five in the poll, voted for by Radio Times readers.
Literary monster Dracula (1931), Godzilla (1954) and killer doll Chucky from Child’s Play (1988) are also in the top 10.
Jabba the Hutt from the Star Wars movies, The Fly, The Terminator and the Tyrannosaurus Rex from Jurassic Park all featured in the longlist.
The poll received over 2,000 votes.
