===Models and puppets===
{{Main|Scale model|Puppet}}

[[Scale model|Models]] have been an essential tool in science fiction television since the beginning, when [[Buck Rogers]] took flight in spark-scattering spaceships wheeling across a matte backdrop sky. The original ''[[Star Trek: The Original Series|Star Trek]]'' required a staggering array of models; the [[Starship Enterprise|USS ''Enterprise'']] had to be built in several different scales for different needs. Models fell out of use in filming in the 1990s as CGI became more affordable and practical, but even today, designers sometimes construct scale models which are then digitized for use in animation software.

Models of characters are [[puppet]]s. [[Gerry Anderson]] created a series of shows using puppets living in a universe of models and miniature sets, notably ''[[Thunderbirds (TV series)|Thunderbirds]]''. ''[[ALF (TV series)|ALF]]'' depicted an alien living in a family, while ''[[Farscape]]'' included two puppets as regular characters. In ''[[Stargate SG-1]]'', the [[Asgard (Stargate)|Asgard]] characters are puppets in scenes where they are sitting, standing, or lying down. In ''[[Mystery Science Theater 3000]]'', the characters of [[Crow T. Robot]] and [[Tom Servo]], two of the show's main (and most iconic) characters, are puppets constructed from random household items.
