By the way, why do they call a Gaffer a Gaffer? Why dont they just call him Electrician?
Because he's the head of the department and you call the old man or boss The Gaffer in the U.K.
Ever read Lord of the Rings? Gaffer Gamgee, Sam's dad. Actually meant "Old man Gamgee"
So there you go.
Most Gaffers are burly but fat older dudes who chomp cigars and take no shit while lugging heavy shit (
and often living in the rafters of the set) and being awesome at making things look pretty. They are also the best buds with the DP/Cinematographer. They are the closest thing to a blue collar artist you'll ever see.
