What do “armful” and “sweep” mean in this conversation?
I watched an old movie released in 1933, and there is a conversation I feel confused about.
Jimmy: Do you want me to give you a word picture of what's going on in that man's mind when he's talking to you about your book?
Jimmy: It's as searching as Huxley. Hm. Hm. What a lovely armful. It has all the sweep of the elder Dumont. Ah. Hm. What a charming interlude I'm going to have with this girl.
Mary: You're testing an old friendship very hard, Jimmie.
I cannot understand what "armful" and "sweep" mean in Jimmy's words. I know it is a very old movie so it may be hard for the modern audience to understand, but I'm wondering if anyone can understand it. Thanks in advance.
