Final answer:
In 'Ender's Game,' wall carpeting is used for practical filmmaking reasons such as cushioning actors and providing a surface for CGI effects to simulate weightlessness. Additionally, it assists in soundproofing the set.
Step-by-step explanation:
The carpeting on the wall of the shuttle in Ender's Game is there primarily for practical reasons related to the storytelling and filmmaking process. In movies such as Ender's Game, computer graphics are often employed to simulate weightless environments. This simulation requires smooth surfaces for the actors to interact with in order to create the illusion of moving through zero gravity. The carpeting helps to cushion the actors during their movement and provides a uniform background that can be easily altered or replaced with CGI effects post-filming. Furthermore, carpeted walls can also contribute to the soundproofing of a set, reducing external noise interference during filming.
