I don’t think I’ve even mentioned Bogart’s character’s name. It’s Dix (Dixon “Dix” Steele). Here’s how Dorothy B. Hughes, who wrote the novel, describes him: “A young fellow, just an average young fellow. Tanned, medium light hair with a little curl, medium tall and enough weight for height. Eyes, hazel; nose and mouth right for the face, a good-looking face but nothing to remember, nothing to set it apart from the usual.” Be grateful to the casting director for ignoring all that, though I do like “enough weight for height”.⠀
