Greydon Clark will never learn. The man has written and directed a slew of thoroughly awful films, gaining some slight notoriety in the late seventies for Satan's Cheerleaders and The Return. Rest assured this particular piece of horse hockey is no better than the films he made at the "pinnacle" of his career.
Skinheads (I'm sure you can guess the plot, theme, and overbearing moralization from the title alone) is notable solely as a turning point-- well, okay, maybe an S-curve-- in two careers. It's one of the last films of Rifleman star Chuck Connors, as the grizzled hermit who takes a stand against the Evil Skinheads(TM), and it was the first big-screen role for Brian Brophy, who's since gone on to be a solid character actor in "serious" films (The Shawshank Redemption, White Man's Burden, et al.). Comparisons with American History X are inevitable, and will be uniformly unfavorable; where Tony Kaye gave us a band of halfway intelligent skinheads with a truly dangerous and thoughtful leader, Clark's bunch of halfwits are incapable of anything but the kind of moral posturing one might expect from a band of chimps exposed to nothing but reruns of That Girl for years on end.
The one bright spot in this film, ironically, is the late Dennis Ott as Brains, the slow-on-the-uptake skinhead who provides the group's muscle and the overwhelming majority of the film's levity. Sadly, Ott, who passed away from AIDS-related complications in 1994, never got another role this big. It's worth a free rental to watch him here. **
