Among the vast oeuvre of Isaac Asimov are mysteries with the futuristic detective Elijah Baley and his robot partner R. Daneel Olivaw. One is The Caves of Steel (1953), which was adapted for British television in 1964. Here are some tantalizing (if low-budget) clips from the episode for Story Parade, which include a glimpse of Peter Cushing.
