Your first thought may be to consider the awful effect of one of them being blown up in part one. Rather than use a dummy ragdoll knight, they put a guy on a trampoline and filmed him going vertically upwards, hands at his side when he was apparently hit by a grenade. Its (just) better than throwing confetti towards the camera and ducking off screen. But instead, there's something else that completely ruins this 1989 serial if you care to do a little research. This was one of the first acting jobs for one Marc Warren, who managed to get a job as an extra in part one. Marc Warren, who you may know as Elton from Love and Monsters. Hes not all of them, but he could be any of them. Have fun being unable to stop yourself guessing which.
