This is Mark Coulier. He's a makeup artist with two Oscars, two BAFTAs, a ton of amazing credits — and he worked on all eight Harry Potter movies.
He recently dropped by BuzzFeed to turn us into zombies, and while he was here, we picked his brain (haha) about his experience working on the magical films.
1. The underwater scenes from Goblet of Fire were "really intense," and so was the makeup. The gills Harry grows after eating the Gillyweed took about an hour and a half to apply and were made of silicone.
2. The interior gill filaments were made out of silk so they would flow nicely and billow underwater.
3. But doing Daniel Radcliffe's makeup was a lot of fun.
4. Ralph Fiennes only had his Voldemort makeup applied 60 to 70 total times throughout all the movies.
5. And 40 to 50 of those applications were in the two final films alone.
6. It took three people two hours to apply his makeup every time — which is actually pretty quick.
7. Voldemort's makeup included eyebrow blockers, a "little intricate paint job all over him," darkening of the eyes, and a lot of vein transfers — aka temporary tattoos — as well as fake teeth and fingernails.
8. His famously creepy nose was all CGI, and it took a while to decide whether or not they wanted his nose removed or not.
9. Partly because they wanted to use as much of Ralph's real face as possible, so he was still recognizable.
"When they’re paying that kind of money for a major star, you don’t want to cover him up so he’s unrecognizable. And Ralph’s got such a striking look that we wanted to use him and not have the makeup be too intrusive."
