I like the eerie killing of Michael Hordern in the Bermondsey tenement building, though Robert Morley's pie-eating is certainly unforgettable.
As for Price, well he gave "
a fascinating performance, but he was madly overacting as usual, but you must admit he did know how to make an exit."
Incidentally the stage adaptation featured Jim Broadbent as Lionheart and Rachael Stirling (Diana Rigg's daughter) as his daughter.
