Shada was well on its way to being filmed before a technicians strike derailed it, they made one more attempt to finish it then shelved it. Dirk Gently got there first before the later reconstruction and novelisation and, now I notice, they've done a novel of "The Krikkitmen" - after the story appeared in 'Life, the Universe and everything' (I think). May have to pick that book up - and see if I can find some 28mm androids to convert (Hasslefree already do the cricket bats).
