Now most people say this is a ridiculous and pretentious piece of clap-trap but they're wrong. This is considerably better than most crappy '80s period movies i've seen. Joan Crawford plays Monica Rivers, a sexy owner of The Great Rivers Circus who wastes no time in taking advantage of the publicity brought in by a string of murders - two of which happen during a performance - and falls under suspicion, all thanks to the loud-mouth Matilda (Diana Dors). She seems to fall apart with each tragedy and soon everyone - including her daughter (Judy Geeson), the cool-dude tightrope walker (Ty Harding) and the pompous manager (Michael Gough) - wonders if she's gone 'BERSERK'. Despite a few airy-fairy conversations and ludicrous puns, BERSERK is definitely a cult classic and should be seen if you've never been to a circus. It makes good use of suspense and you don't know who is getting it next.
