No Blade of Grass (1970) 7.5/10
End-of-the-world global famine movie from England. It drags in the middle, but the opening and fianle are great. A true lost classic, this one isn't available on DVD or VHS - but I had someone burn me a DVD from a film library.
It pre-dated and was a huge influence on Soylent Green and the second half of the film is pure Road Warrior.
