This is a very cool Rick Baker signature with a great story behind it Emperor Palpatine, made his first on-screen appearance in the second (or fifth?) Star Wars film, The Empire Strikes Back in 1980.
This was before Ian McDiarmid was cast to play the character in Return of the Jedi and the prequel trilogy.
Instead, makeup director Rick Baker dressed up his wife, Elaine Baker, for the part.
In post-production, a chimpanzee’s eyes were superimposed onto Mrs. Baker’s face to make the appearance of the Emperor more unsettling.
The voice was provided by a man, veteran voice actor Clive Revill.
The scene was later re-shot with McDiarmid and some slightly different dialog So to have Ricks signature on this is way cool, its not the chimp eye photo but fantastic none the less, have to thank my friend Sue for this
