"When they've got somebody extremely tall bringing their character to life, it's got the human touch on it," Fingleton says of Game of Thrones' giant strategy. "I guess you can always tell when stuff is just computer-generated. Don't get me wrong, it looks cool, but some directors and shows, they want it to have this human touch on it."
Like last night's giant action -- Game of Thrones' version of Hulk vs. Loki -- Fingleton's Mag the Mighty is a mix of live action, costumed acting and clever CGI. To showcase the "human touch," Game of Thrones crew members designed Mag's costume to be nimble, allowing a tall actor's particular gait to read on screen. Fingleton could run, jump, swat soldiers away in combat, lift the castle's gates, and ride a wooly mammoth (which, in the pre-special effects shoot, is a glorified mechanical bull with shaggy hair). The costume is custom-built to the actor's exact dimensions, in a process that's basically plaster-of-paris mummification. Once Game of Thrones costumers have a cast of their future giant, they fill the mold with fiberglass and create a mannequin replica, which can be outfitted with dressing from beyond the wall.
