The plot premise of Evening in Byzantium really impressed me at the time as being a semi-plausible way that terrorists might be able to attack the US, and even before 9/11 I would sometimes think of it whenever the government proposed spending billions of dollars on missile defense systems that were supposed to protect us from "rogue states".
But the other thing about it that struck me and stayed with me over the years was how strange the casting was. Glen Ford as a scriptwriter wasn't too hard to accept because he becomes an aging action hero as the plot develops. But Eddie Albert was an odd choice in such a serious role, and Shirley Jones (Mrs. Partridge, for heaven's sake!) as a junkie was just bizarre.
