Star Trek Into Darkness Edit
Conceptually, the Enterprise's warp contrails were intended to be a new addition made to the ship between Star Trek and Star Trek Into Darkness. Regarding the addition of the contrails, Lindelof explained, "That was driven by a few things. One was to show the audience that Scotty has made modifications to the Enterprise between the two films [...] since Scotty is now the [chief] engineer." The filmmakers were mindful that, in adding the warp contrails, they didn't deviate from canon too much, such as if they had added a cloaking device to the Enterprise's systems instead.|The warp contrails were depicted with CGI. Said Lindelof, "Roger Guyett, our visual effects supervisor, took J.J.'s phrase 'warp contrails' and ran with it [....] Roger tried a few tests, some of which felt a bit too radical, but it was basically us [...] saying 'wow, that looks cool.' And we went with it."
