Jesse Eisenberg doesn’t look like himself in the promotional photos for “The Art of Self-Defense” (2019). Dressed in his karate outfit, fist and jaw clenched, he looks like a 1960s British spy. At least he does to me. And perhaps to himself, because the reason his mild-mannered character takes karate is to become more masculine. That’s the pivot point upon which this dark, dark comedy rests. There’s humor and horror within his desire to become the thing he’s afraid of, and we are witness to both. But the thing that makes this film worth watching is the courageously quirky dialog.
