If there’s a vanguard of comic insecurity, Charlie Kaufman is leading it. In the seven films he’s thus far written (and more recently, directed), Kaufman’s characters are often overwhelmed, crippled by an oil/water mix of ego and self doubt. It’s important to maintain the distinction between an author and his voices, but with Kaufman it’s just lip service — he is deeply embedded in his work. In the stop-motion animated Anomalisa, this penchant for gluttonous self-examination produces Michael Stone, a man of misanthropy and mania. Or, in other words, a man.
