Just watched an 87 minute film written by Rod Serling, entitled Carl for Another Christmas(1964). It's obviously based on Dickens classic, but updated to the 1960s. It is however extremely appropo to today's society's issues. If you have the time, I recommend it highly.
Dickens Scrooge was based on Thomas Malthus who talked about overpopulation. Is that issue covered in the film?
Actually, it is tangentially..
