Planet of Giants
'Planet of Giants' is a fairly forgotten story, this imbalance only redressed by its recent video release. Prior to seeing it for the first time some months ago, my only knowledge of it came from the Target Novelisation, which IMO is one of Dicks' two worst novelisations (the other being 'The Space Pirates'). Consequently, I'd decided it was crap actually seeing it forced me to re-evaluate it.
The most obvious feature of 'Planet of Giants' is of course the miniaturization of the TARDIS crew. In essence, this is pure gimmick, for which the rest of the story is thus tailored. Nevertheless, it is an effective gimmick, well realized thanks to the superb "giant" sets, especially the sink in Smithers' lab and the telephone, both of which are realistic and convincing. The fly is especially impressive for 1964, particularly when compared to the feeble realization of another giant fly years later in 'The Green Death'. The challenges presented by their diminutive size thus preoccupies the Doctor and his companions throughout, making for an interesting story, as they face danger not from Voords and Sensorites or historical villains, but from cats, flies, and insecticide. Not only the TARDIS crew, but also the actors themselves, rises to these challenges, convincing the viewer that the characters really have been shrunk. To add an extra dimension to this plot, we have the DN6 subplot, with the inch-tall travelers struggling to bring to justice Forrester and Smithers for the murder of Farrow. One of the main criticisms often leveled against 'Planet of Giants' is that it has a sparse plot, and whilst this is certainly true, it is I think entirely justifiably; coupling a miniscule story with a Dalek invasion or a complex historical plot would have been a logistical nightmare for the production team and certainly outside the confines of a mere three-parter. The DN6 subplot is basic, but effective it presents a threat to the Doctor and his companions and gives them a goal, whilst limiting the story to (more or less) a single house and garden. Forrester, Smithers and Farrow are played with conviction, despite not really having much to do. Of the three, Smithers is the most interesting, as he is at least motivated by a overall desire to do benefit mankind, forcing him to struggle with is conscience in the wake of Farrow's death, and eventually accept that DN6 is too deadly to ever be marketed. The obviously conscientious Farrow is quickly dispatched, but again a three dimensional character based on what little we see of him. Forrester is the least successful, coming across as little more than a stereotypical ruthless businessman, but it is this ruthlessness that drives the plot due to his murder of Farrow and he thus fills an important role. The other two characters, Burt and Hilda Rowse, are again well acted during their brief appearances and again their brief scenes are crucial to the plot. Hilda is particularly annoying for me, since I loathe the kind of curtain-twitching busybody neighbour that she represents, but it is her nosiness that leads to Forrester being brought to well-deserved justice. The fact that a character only present in two scenes can still manage to frustrate me in this way is a sign of effective, if functional, characterisation.
The main problem with 'Planet of Giants' is that it lacks a sense of any real danger. Despite being small enough to be at considerable risk from virtually everything that they encounter, the story fails to really convey a sense that the Doctor, Susan, Ian and Barbara are in real peril, the Doctor in particular seeming to enjoy himself rather too much throughout. Even when climbing the drainpipe and almost being drowned in the sink, he gives the impression that he is merely out on a stroll, which robs the miniscule sub-plot of momentum after the initial impact of the gimmick, the story is a bit too leisurely to be truly involving. Even when Barbara is poisoned by DN6, there is little sense of danger, despite the decent acting from both Russell and Hill. Her illness is established and gets progressively worse, but is suddenly sidelined in episode three, with both Barbara and the Doctor insisting that they have to bring Farrow's murder to the attention of the authorities, despite the enormous risks inherent in delaying their return to the TARDIS and whilst Barbara just flutters a hand now and again and looks vaguely tired. In short, the TARDIS crew should feel and seem more vulnerable. I've already mentioned that the difficulties inherent in the realization of the regulars' diminished circumstances dictate the limitations of the overall plot, but the story could still have been made more gripping within that plot. Had Ian and Barbara been, for example, been found and trapped by Smithers, it would have fitted easily into the overall story and added an extra dimension of excitement, as their rescue would have presented greater challenges to the Doctor. Instead, the impression is given that the Doctor and friends could have defeated Forrester and Smithers in their sleep, and this is not helped by the swift and (so far as we know) easy return to the TARDIS in episode three. And Susan, who I've barely mentioned here, gets nothing whatsoever to do, except stand around for the Doctor to explain things to, and bury her face pathetically in Barbara's shoulder when asked to give her opinion on a moral dilemma.
Overall, 'Planet of Giants' is slim pickings, but not an entirely unsuccessful experiment. The gimmick works, and just about keeps the attention despite the increasingly flagging drama as the story progresses. It isn't the strongest season opener, but it isn't the weakest either (stand up 'Time and the Rani') and is basically a whimsical and (for Doctor Who at least) original chapter in the series.
