Question: What is the smallest cast a modern, mainstream, full-length feature film has ever had?
Answer: I can think of a handful of independent features that have only one cast member, but in terms of mainstream fiction films I would have to go with Sleuth (1972), which is a two-man show. It's a psychological thriller set in a 16th-century country mansion where wealthy author Andrew Wyke (Laurence Olivier), who writes diabolically clever mysteries, plays humiliating head games with the younger man (Michael Caine) who's having an affair with his wife.
