Slow motion
Slow motion during weightlessness was inaccurately portrayed; the director had discovered this when riding the Vomit Comet, but he kept the slow motion to meet audiences' expectations. Another purposeful inaccuracy was the "whooshing" of the ship, despite there actually being no sound in the vacuum of space; Cox later mentioned in the BBC's "Stargazing Live" programme in January 2011 that this was simply because without accompanying sound, the CGI shots seemed "cheap".
