The first is well worth reading for a comprehensive look at the film. The second is worth keeping an eye on while watching it, plus they've got a nice little writeup on it as well.

Hippies, indians, communes, psycho-drama (wtf???), vigilantes ... you name it. This movie is the height of weirdness. Not as pure and simple a commentary as the Walking Tall series. But still its equal in terms of entertainment value. I'm pretty sure that casting Howard Hessman was the downfall of this movie. But the scene where the psychodrama actors act out a street mugging, confounding the local cop ... that's a scene I personally find incredibly hilarious since it fits with much of the Rocky Horror schtick I've got working.

Of note, there was a follow-up done later on, titled Billy Jack Goes To Washington. It was directed by Frank Capra Jr. and was a remake on the classic Frank Capra original. By all measures, it bombed considerably. Legend has it that a US Senator was in attendance at a private screening with Tom Laughlin, the actor/creative genius behind the Billy Jack franchise, and he went ballistic on him after viewing it. I'll take a pass on getting that DVD and keep my eye open for the Walking Tall series on DVD instead. Buford Pusser could kick Billy Jack's ass with that stick of his and it wouldn't even be a close contest. I mean the guy got shot up more than swiss cheese or Keith Richards and he still lived to make sequels.
