One as close as possible and a more subtle version.\u201d<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tSubtlety proved the best choice, requiring fewer prosthetics but multiple stages of makeup to account for eye swelling, a broken nose and a lost tooth. \u201cOf course, I could do more, but during filming, there would be a lot of scenes, so I had to consider the practicality of filming,\u201d Hiro adds. \u201cThere are more elements on the face, so I had to do more touch-up and repair work. That would take time.\u201d<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tWhat motivated Hiro to undertake Johnson\u2019s transformation into Kerr was the fighter\u2019s immense physicality and emotional complexity. To prep, the prosthetics designer studied the acclaimed 2002 HBO documentary The Smashing Machine: The Life and Times of Extreme Fighter Mark Kerr.<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\t\u201cI was fascinated by the psychology of people who do Ultimate Fighting and who Mark Kerr was,\u201d Hiro says. \u201cHe was such an aggressive fighter but so soft-spoken. He spoke almost like a baby. And Dwayne worked really hard to make his body look like Kerr\u2019s.\u201d<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tUnlike Hiro\u2019s transformation of Gary Oldman into Winston Churchill for The Darkest Hour and Charlize Theron into Megyn Kelly for Bombshell, the two-time Oscar winner had to deal with a new X factor: lots of sweat during the fighting scenes, which required extra touch-up and repair work. Each fight also had its own physical characteristics.<\/p>\n<p>\t\t\t\t\t\t<img loading=\"lazy\" class=\"c-lazy-image__img lrv-u-background-color-grey-lightest lrv-u-width-100p lrv-u-display-block lrv-u-height-auto\" src=\"https:\/\/www.hollywoodreporter.com\/wp-content\/themes\/vip\/pmc-hollywoodreporter-2021\/assets\/public\/lazyload-fallback.gif\" data-lazy-src=\"https:\/\/www.europesays.com\/ie\/wp-content\/uploads\/2025\/12\/Print-Issue-32B-rep_BTS-Johnson-Kerr-Publicity-EMBED-2025.jpg\" alt=\"\" data-lazy- data-lazy- height=\"563\" width=\"1000\" decoding=\"async\"\/><\/p>\n<p>\t\t\t\t\t Kazu Hiro decided that Dwayne Johnson didn\u2019t need to look exactly like MMA fighter Mark Kerr in The Smashing Machine, for the \u201cpracticality of filming.\u201d Johnson wore 22 prosthetics and a wig.<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\t\u201cAfter a few days, we started to know the chemistry of the sweat and where they to tend to sweat more,\u201d Hiro explains. \u201cBased on that, we learned which area comes off first \u2014 where it starts to detach from your face. So one thing to understand is what kind of sweat they have and how it comes through the skin. That weakens the adhesive. So we probably have six or seven different kinds of adhesive.<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\t\u201cDwayne sweats a lot on his head but his face is quite normal,\u201d Hiro continues. \u201cI worked with [special effects] makeup artist Glen Griffin to figure out the best combination of adhesives to withstand the sweating. Also, Dwayne has a lot of body tattoos that had to be covered up, and then we added Mark\u2019s tattoos on top.\u201d<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tIn total, there were 22 prosthetic pieces and a wig applied to Johnson via a team of nearly 20 makeup artists working four hours each day (including Johnson\u2019s personal makeup artist, Bj\u00f6rn Rehbein). These included a new brow bone, scars and a cauliflower ear.<\/p>\n<p>\t\t\t\t\t\t<img loading=\"lazy\" class=\"c-lazy-image__img lrv-u-background-color-grey-lightest lrv-u-width-100p lrv-u-display-block lrv-u-height-auto\" src=\"https:\/\/www.hollywoodreporter.com\/wp-content\/themes\/vip\/pmc-hollywoodreporter-2021\/assets\/public\/lazyload-fallback.gif\" data-lazy-src=\"https:\/\/www.europesays.com\/ie\/wp-content\/uploads\/2025\/12\/TSM_00901-EMBED-2025.jpg\" alt=\"\" data-lazy- data-lazy- height=\"667\" width=\"1000\" decoding=\"async\"\/><\/p>\n<p>\t\t\t\t\tWriter and producer Benny Safdie (left) with Hiro.<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tHiro had to bring Johnson\u2019s brow bone down and add a fake eyebrow to make it closer to Kerr\u2019s heavier eyelids and bone structure. The prosthetic eyelid required extra tweaking. \u201cThe thickness was almost half an inch,\u201d Hiro notes. \u201cSo if we glued that piece down right on his eyelid, when he blinks, he cannot blink naturally. So I made a core piece that attached to the positive mold.\u201d<\/p>\n<p>\t\t\t\t\t\t<img loading=\"lazy\" class=\"c-lazy-image__img lrv-u-background-color-grey-lightest lrv-u-width-100p lrv-u-display-block lrv-u-height-auto\" src=\"https:\/\/www.hollywoodreporter.com\/wp-content\/themes\/vip\/pmc-hollywoodreporter-2021\/assets\/public\/lazyload-fallback.gif\" data-lazy-src=\"https:\/\/www.europesays.com\/ie\/wp-content\/uploads\/2025\/12\/TSM_Scans_00315-EMBED-2025.jpg\" alt=\"\" data-lazy- data-lazy- height=\"802\" width=\"1000\" decoding=\"async\"\/><\/p>\n<p>\t\t\t\t\tIndividual fight scenes garnered unique challenges, as sweat made the adhesives of the prosthetics come off. <\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tA separate prosthetic to represent eye swelling during fights had to be applied in real time. \u201cAs we progressed the scene, we added more pieces on top of the likeness makeup,\u201d Hiro explains. \u201cWe added color and showed the progression during the filming. Also, we had the scene where he shaved his hair in the middle of the film. For that, I made a silicone bald cap on top of his bald head. I punched the individual hair [inserting single hair strands into a silicone or foam latex appliance] so it can be [treated like real hair] and shaved by a real barber.\u201d<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tThe makeup team\u2019s careful work on set was not without incident. \u201cOne time, the tip of [Dwayne\u2019s] nose came off,\u201d says Hiro. \u201cIt had to be repaired, but it would keep happening.\u201d<\/p>\n<p>\t\t\t\t\t\t<img loading=\"lazy\" class=\"c-lazy-image__img lrv-u-background-color-grey-lightest lrv-u-width-100p lrv-u-display-block lrv-u-height-auto\" src=\"https:\/\/www.hollywoodreporter.com\/wp-content\/themes\/vip\/pmc-hollywoodreporter-2021\/assets\/public\/lazyload-fallback.gif\" data-lazy-src=\"https:\/\/www.europesays.com\/ie\/wp-content\/uploads\/2025\/12\/TSM_Scans_00358-EMBED-2025.jpg\" alt=\"\" data-lazy- data-lazy- height=\"669\" width=\"1000\" decoding=\"async\"\/><\/p>\n<p>\t\t\t\t\tJohnson (left) as Kerr and Oleksandr Usyk as Igor Vovchanchyn in the film.<\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tSee more on the making of The Smashing Machine and other <a href=\"https:\/\/www.hollywoodreporter.com\/t\/awards\/\" id=\"auto-tag_awards_1\" data-tag=\"awards\" rel=\"nofollow noopener\" target=\"_blank\">awards<\/a> contenders at THR\u2018s dedicated site for behind-the-scenes stories at <a href=\"https:\/\/www.hollywoodreporter.com\/e\/behind-the-screen\/\" rel=\"nofollow noopener\" target=\"_blank\">THR.com\/behindthescreen.<\/a><\/p>\n<p class=\"paragraph larva \/\/  a-font-body-m     \">\n\tThis story first appeared in a December stand-alone issue of The Hollywood Reporter magazine.
