The sheer physical commitment required for the 2000 live-action film is legendary. Jim Carrey's transformation into the Grinch required an intense process that few actors could endure.

• The Torturous Makeup Process: Jim Carrey spent a reported 92 days in the Grinch makeup chair. The process initially took over eight hours, eventually being reduced to three. Carrey found the experience so unbearable that a Navy SEAL was brought in to teach him torture resistance techniques to help him cope with the prosthetics and contact lenses.

• Martha May Whovier’s Real Nose: The film’s makeup team initially planned a prosthetic nose for Christine Baranski (Martha May Whovier). However, due to her naturally upturned nose, the team considered letting her use her own, a rare exception to the extensive Who prosthetics, though ultimately they used a slight prosthetic to blend with the other Whos.
• The Forgotten Who: The role of young Martha May Whovier was played by actress Landry Allbright, who also had a memorable role in the film *Con Air*.
