Dipping into the mid-70s well again, we find this 1973 SciFi flick by none other than Star Trek creator Gene Roddenberry. Set post-apocalyptic where humankind nuked the crap out of the planet, and people are digging out, rebuilding, and empire building. Mariette Hartley provides some nice eye candy, and ya, Roddenberry gets a bit preachy. No surprise there.
