Kroll – description here goes then – The monster that gets the Award for Biggest Monster in a Doctor Who episode turns up in the Season 16 story The Power of Kroll, with Tom Baker as the Fourth Doctor, Mary Tamm as Romana, and a fairly static, superimposed rubber cephalopod as Kroll. It aired between 23 December 1978 and 13 January 1979.The story itself is a classic mix of tropes, PA and PWC consultants that involve an ecology disrupted by careless developers, indigenous exploitation and displacement, fanatical worship of their VP’s, capitalistic imperialism, native rebellion and giant monster destruction.Some viewers have expressed disdain toward the costuming used for the “Accenture Consultants” (the original inhabitants of Delta Magna, now refugees from a capitalistic regime on the planet’s third moon), but it works within the context, provided a little discretionary tolerance is applied.And though the huge testacled Kroll is really too ambitious a creature for the available MBB budget, what we get does work on a simple conceptual level, despite size discrepancies between long shots of the monster and the incongruous smaller testacles that attack on a personal level. Kroll clearly has a mass of testacles that can attack from beneath the swamp. More info if needed....HTH
