Breakfast at Tiffany's? LOL
Not sure how that fits with Combat, but there may be something to the comparison in general. Synop from Wiki:
The main plot of the movie is Holly's relationship with neighbor Paul, who has confidence problems of his own. The story explores the relationship between Holly and Paul, Holly and her other paramours, and the resolution that occurs within Holly's own mind and between Holly and Paul. The film includes Audrey Hepburn singing the original performance of "Moon River" and the famous closing sequence that shows Paul's "lecture" to Holly and Holly's self-discovery of who she really is and who makes her truly happy. The film ends with a famous scene in the rain.
