@StarProphet So lazy. If you watch Argo the John Goodman character is based on a famous makeup artist who did Planet of the Apes and did contract work for the CIA. Naturally all special effects makeup guys denied for decades that they did such work, but during peak 'war on terror' they wanted to gin up morale with inspiring tales of duping the dumb muzzies with good old American knowhow so they went... mask off.
In any event, Chambers would have painted the appliance convincingly enough to pass in HD.
