The Eagleman Stag is an award-winning stop motion animation film directed by Mikey Please with a striking visual aesthetic. The website for the film offers a "How It Was Made" video that is, in itself, highly engaging, but comes with a warning: "BEFORE WATCHING THIS, WATCH THIS. THEN ASK YOURSELF IF YOU REALLY WANT TO KNOW." If that link puts you off "making of" media, then perhaps you can watch more of Please's work: Spectacular View, Zombiegotchi, Seven Legs, Animation Tag Attack EP-10, title sequence for The Rabbit Lover, Picasso Pictures Christmas Card, etc.
