One of my favorite movies of the 50's science fiction era was Them!, a movie about giant mutant ants attacking people. This would be a perfect movie to redo with modern special effects. Above is my idea of what would constitute a good remake: lots of flamethrowers, giant ants (of course), all taking place in New York City. New York City is photogenic enough for lots of monster attacks. Another good city would be Paris, due to lots of sewers.
