Twenty-four movies at the multiplex and nothing to see. That's the sad reality of moviegoing in most of Broward and Palm Beach counties. The multiplexes continue to amaze us with the sheer quantity of utterly banal schlock they screen each week. (On exactly how many screens can you show Enemy of the State, to take one example, and still make money?) Shadowood 16 in Boca Raton, the Carefree Theatre in West Palm Beach, and Sunrise 8 in Fort Lauderdale occasionally break through the tedium, screening rarely seen independent films such as Central Station in recent months. But the most consistent venue for catching provocative, intelligent movies is the Gateway Cinema. The almost-50-year-old Fort Lauderdale landmark has over time transformed itself into a redoubtable art-house theater. One could see the restored version of Orson Welles' B-movie thriller Touch of Evil, as well as the luminous Giulietta Masina in Fellini's Nights of Cabiria, not to mention stellar contemporary films, such as Little Voice and Happiness, that did not really interest the multiplexes.
