Greyhound is a curious film in that it flies in the face of one’s expectations. When I (and possibly others) see an advertisement or trailer for a World War II movie starring Tom Hanks, I naturally assume that the lead actor has been hired for his prodigious acting talent and that he’ll be providing an in depth character study. I was expecting Greyhound to be the story of an untested US Naval Commander enduring an ordeal by fire on his first escort mission. And that is to a degree what director Aaron Schneider provides but instead of the narrative arc focusing on Ernest Krause’s emotional struggles with his duties, we instead get a docudrama focusing on the technicalities of naval warfare. The latter approach is certainly engaging and at times tense and exciting but this decision narrows the appeal of the film. I personally would have preferred the former.
