It used to be a running gag that the original Doctor Who was hamstrung by minimal budgets and dodgy sets, but my recent ambles down Memory Lane - most recently Ambassadors of Death, Colony in Space and Claws of Axos - refute that accusation. Ambassadors, for instance, features a military convoy being attacked by helicopter (no stock footage there), whilst Claws offers a large cast of extras and the exotically organic interior of the Axonite spacecraft, even if the true form of its crew does resemble a Michelin Man covered in spaghetti. One does wonder whether Jon Pertwee would have stayed longer, had later serials such as Planet of the Spiders managed to keep up that standard.
