Even though CGI has evolved to the point that studios can literally conjure up skyscraper-sized monsters, drop them right from the sky and make them look totally believable, movies still look best when shot with a mix of both Hollywood magic and practical effects. However, when you think of practical effects, the last thing that crosses your mind is fake armpit sweat.
After all, why would a movie call for its actors to look all sweaty and dirty? Wouldn't that pose a problem instead?
Well, if you're shooting a movie with people wearing spandex costumes and capes while making it look like they are in a burning hot desert or a tropical jungle, such as with James Gunn's The Suicide Squad, it makes a lot of sense for your characters to look a bit disheveled and scruffy.
Still, to hear of staff members literally dabbing actors with fake sweat is something that sounds made up, but believe us when we say that this is all true.
