I guess that your paragraph is referring to Marina, Mr. Oswald's wife. Am I right? Well, then, the paragraph means that she was constantly asking him for money to buy new gadgets and to buy tickets to movie theaters. (This was in the 1950's. So "gadgets" would refer to new inventions that appeared in those days. For example, I do NOT know when the electric can opener was invented, but when it did go on sale, it would be considered a "new gadget" for the kitchen.) As I said, "movie money" would be money that she would use to patronize movie theaters.

The new gadgets would refer to new technology that was coming out at the time. Depending on the era, for instance a new gadget for my parents when they were young would have been an electric washing machine or tumble drier and since then my parents have seen many new gadgets, remote conbtrol light switches, MP3 players etc. Movie money probably means she wanted to go to the cinema to see the latest films.

Since it would mean the same, you could shorten the translation of this paragraph and just say that they "had a regular American marraige." Okay...I'm just being funny:-)
