I am in Palm Beach for a few days, so here goes:
Film: The classic is Key Largo; Bogie’s speech about Edward G. ("more, you want more…") is a (the?) classic statement of behavioral economics. An honorable mention goes to Wild Things, a hot and underrated work of teen film noir. Of course Body Heat was set in Florida as well. As for comedy, Jim Carrey’s debut feature Ace Ventura: Pet Detective, set in Miami and environs, was made before his brilliant comic talents ossified.
Music: The Allman Brothers, Ray Charles, and Tom Petty are the only competitors I can think of. They are all overrated, but I will opt for Charles’s "What’d I Say?" Tampa Red was pretty good, but often he is attributed to Georgia.
Art: Many notable Americans painted Florida, but how about an artist who is truly of Florida? I’ll opt for the Haitian Edouard Duval-Carrie, here are a few good paintings by him. And here is Kevin Grier’s favorite Duval-Carrie, scroll down to the bottom.
The bottom line: I love Miami Art Deco and roadside architecture, but doesn’t Florida feel just a wee bit underrepresented on the lists of artistic greats?
Addendum: A number of readers argue persuasively that the Allman Brothers should belong to Georgia, not Florida.
