Just FYI:
Red Dawn is being re-made, which was supposed to be released in 2010, but it's been delayed with no definite release date. -- Unfortunately, I've heard that a few die-hard fans read the script and say it's full of political correctness, bias agendas and propaganda. I'll save my critique until after I've seen it.
Also, there was a new movie in Australia called, "Tomorrow, When the War Began" which is very similar to Red Dawn. It was decent, but no Red Dawn.
My favorite 'survival' program was the "Jericho" TV series..
