The Outcasts

Speaking of bikers as outsiders, here's a BBC documentary about a Norfolk Hell's Angels gang called The Outcasts. Originally shown in 1985, it has its share of odd images and amusing characters, but is shot through with a dark seam of real life horror which is only fully exposed right at the end.

Perhaps befitting their status as folk devils and leather clad outsiders, bikers mostly feature as a threat in British horror films, although their self-consciously tough image is just as often the subject of mockery, parody or homoerotic innuendo in other genres.
