"The hardest thing we did was shave Taron's hairline further back [on his forehead] and to thin his hair out," Georgiou revealed. "That was brave of him, as he had to live with that for the run of the film." Among the other major changes Egerton went through to transform into John: prosthetics to create under-eye bags and deep smile lines, heavier eyebrows, and a bald cap.
"I called in Barrie Gower of [FX makeup company] BGFX to codesign the prosthetics. We had two prosthetic artists and myself create that look for each [scene] Taron was in."
