The makings for a good thriller are here: a series of bizarre murders plagues a traveling circus as it journeys across England. Unfortunately, the film's pacing is slow and unimaginative. Scenes tend to run long and they've not been shaped to create any real suspense or urgency. Occasionally the film simply stops for footage of circus acts which, though mildly interesting, do little to advance the plot. Even the revelation of the killer's identity proves disappointing since this revelation doesn't seem to grow out of past events but has simply been "tacked on."

Despite these faults, there's a curiously likable quality to "Berserk," and Joan Crawford's damn-the-torpedoes performance as the circus owner lends it a certain "campy" charm. Especially amusing are her romantic scenes with Ty Hardin who was about 26 years her junior at the time of the filming.

Ty may have been a bit past his "beefcake" prime which he reached in his "Chapman Report" appearance some five years earlier, but he still looks good here with his shirt off, even though there's a curious reluctance to show his navel.

Rounding out the cast are Michael Gough, Diana Dors, and Judy Geeson. Robert Hardy plays the policeman sent to investigate the murders but his part proves to be superfluous.
