When you've survived a post-apocalyptic world of cannibals and evil gangs, there's nothing left to do but have a 1940s-style dance routine. For some reason, this sequence didn't appear at the end of The Road, so we're including it here.
The awesome dance routine, of course, really comes from the very end of Radioactive Dreams, directed by the great Albert Pyun. Philip and Marlowe have been trapped in a fallout shelter for the past 15 years, with no entertainment other than classic noir detective stories — hence their names and their determination to be Bogart-esque. They have launch keys to one of the last remaining nuclear missiles, so in addition to the cannibals wanting to eat their uncontaminated bodies, they also have gangsters and "disco mutants" chasing after them. It's not much of a spoiler to say they prevail, and succeed in teaching all the mutants how to dance properly. And of course, this movie has classic 1980s post-apocalyptic mutants, with the punk hair and KISS makeup.
