My mate Rene in Australia sent me a link to a series running on TV over there at the moment based on the war between the Comancheros and Bandidos motorcycle clubs in the 1980s, culminating in the infamous Milperra Massacre in 1984: the biggest event in Aussie 'bikie' history.
It's based on a good book called Brothers in Arms, and you can check out some photos from the show here. Looks like they got the period feel down pretty well.
Unfortunately I can't get the first episode to play... looks like it's restricted outside Oz. Anyone know how to get round it?
