  removed a sentence about homages to other space films as being synthesis. I reverted this deletion and justify it below with the quote from the article and the line in the current article.    
 * Numerous articles reference the Ed Harris connection 
 * "Stone goes floating about in nothing but her underwear, it's impossible not to think of Sigourney Weaver's Ripley in Alien."  > "evokes Sigorney Weaver's vulnerable Ripley from Alien" 
 * "Gravity floats on the shoulders of the Pixar giants... [especially] "WALL-E," with its mysteriously somber opening sequence (and with its comic use of a fire extinguisher, which is put to very different use in "Gravity")" > "the extravehicular use of a fire extinguisher from WALL-E"
