31:35 "Face Like a Monkey" -- Disc 14 UPA

A half-hour extra about how the ape make-up would work.

A big hint: you want people with small noses and long upper lips.

It looks unbelievably claustrophobic as they work up the casts.

On the primary masks, every hair is laid individually.

"A lot of rubber.  A lot of hair.  A lot of dental acrylic."

The most sophisticated modern make-ups for this movie take about four hours to apply and one hour to remove.
