The first 'Doctor' film without Dirk Bogarde is also the first to strongly resemble a 'Carry On', with several veterans of the 'Carry On' series (including Joan Sims, also in the original 'Doctor in the House') and several others who became features of the smuttier parallel series. The humour was already becoming more off-colour here (and it's in colour, which the budget of the 'Carry On's didn't yet run to).
We actually see Lady Spratt in this episode (played by Ambrosine Phillpotts), but James Robertson Justice is himself absent much of the time; while in place of Bogarde we get the more abrasive Michael Craig, who plainly doesn't fit in with such frivolity and otherwise steered well clear of either series.
