This sandwich-making man is stop motion animator PES. This is his third food-related stop-motion short, following Western Spaghetti and Fresh Guacamole (Oscar nominated!! Holy Crap!)
He actually has a ton of really amazing shorts. Go look at them on his YouTube channel if you want to have a good day.
"Submarine Sandwich" is set in a vintage-style deli and every sporty ingredient has its own delicious twist. PES says it takes up to 12 hours to make 3 seconds of his films!
