Every movie gets tweaked in the post-production phase. After everything is filmed, there’s still color correction, sound mixing, and visual tweaks to be done.
Computer-generated imagery, or CGI, has increasingly become a useful tool in that process. Sometimes it’s for big things (making it look like a spaceship soars between planets in “Star Wars”), and sometimes it’s small (removing an accidentally visible boom mic).
Often, CGI is used for bizarre — or pointless — purposes. In “Blade: Trinity,” for example, Wesley Snipes refused to open his eyes during one scene, so eyes had to be added with CGI in post-production instead. And in the “Fifty Shades” series, CGI is used to fill out Dakota Johnson’s pubic hair. And then we have Superman’s famous upper lip in “Justice League,” which had to be digitally reconstructed in some scenes because actor Henry Cavill couldn’t shave his mustache.
Here are 18 bizarre times computer effects were used to alter things into movies.
