I commonly see the format:
Main Character(s) and some other important idea
- Harry Potter and the Goblet of Fire
- Alexander and the Terrible, Horrible, No Good, Very Bad Day
- The Three Little Pigs and the Somewhat Bad Wolf
- Johnny Cash and the Tennessee Two
- Fitz and the Tantrums
- Florence and the Machine
And even slight variants:
- Sex and the City
Is there a name for this common construction?
Do the two parts have technical names?
