A strong script and atmospheric direction highlight this tv adaptation of the broadway play. Richard Johnson is a nearly authentic Watson, Simon Callow is a grand and humourous Lesrade and John Castle ( one of my favorite actors ) and Edward Fox lend strong support. the only casting flaw is the American Heston. never a versatile actor he does not invoke Holmes; crusty almost cold manner. he is far too pleasant and at time seems as if he is winking at camera. Too bad they couldn't have used Jeremy Brett. For the best characterizations and story adaptations i wholly recommend his granada television series.
