[custom_adv] Our favorite actors get to play all sorts of characters! They are supposed to look so organic in their roles that they have to literally become the characters. And makeup artists are often their most important assistants. We have collected the brightest examples of outstanding makeup that viewers all around the world will remember for a long time. [custom_adv] Sometimes these transformations are done for the purpose of adapting a non-human character to the screen, sometimes they’re done to help an A-list movie star disappear into a dramatic role, and sometimes they’re done for purely comedic effect. [custom_adv] In any case, the success of these transformations relies on the believability of the makeup effects, as well as the ability of the actor to adapt their mannerisms and persona to completely become someone else. [custom_adv] In honor of Isaac donning blue skin for the latest Marvel sequel, we decided to round up 15 of our favorite instances of actors disappearing behind their makeup. Some of these performances have become iconic in the world of film, while others may completely surprise you. Beginning with En Sabah Nur himself, here are 15 Actors Who Were Unrecognizable Under Their Makeup. [custom_adv] When the first images of Oscar Isaac as Apocalypse appeared on the internet, the film community was a little taken aback. Why would Bryan Singer and company cast one of the fastest rising stars in Hollywood, and then completely obscure him behind thick blue makeup and prosthetics? Fans also weren't thrilled that the character's grey-skinned, blue-lipped appearance was altered (seemingly for no reason), but that's a whole other controversy. [custom_adv] The choice may have caused some surprise, but Isaac is certainly a talented enough actor that his charisma can shine through the thickest makeup job. The character of Apocalypse from the X-Men comics is so intimidating and larger-than-life, some extreme manipulation was always going to be required to bring him to the screen. [custom_adv] So while your mom might be surprised to find out that Poe Dameron is the big bad heralding the four horsemen, the performance will hopefully be remembered as a great use of supervillain makeup effects.
