These three women, throughout the course of the film, chart the courses of their destiny and move towards their big life goals throughout their time working at the titular pizzaria.
Sometimes, a song can make even the smallest moment of a film like Mystic Pizza into a joy.
So, of course, a good way to cement characters like that is having them sing a song like Aretha Franklin’s “Respect,” which cements the plot with a little bit of shorthand through musical convenience.
In the case of that very film, we see our main trio of characters, played by Julia Roberts, Lili Taylor, and Annabeth Gish, singing along to their truck’s radio.
