'Sleuth' was originally written as a play by Anthony Shaffer in 1970. I've never seen it performed as play unfortunately. It was made into two films, in 1972 and 2007. Both starring Michael Caine, except he plays the older character in the 2007 film. I enjoy watching the newer version (the screenplay is written by Harold Pinter) because of the interaction and dynamics between the only two actors, for the entirety of the film. I think it works on a number of different levels and isn't easily compartmentalise, into any one genre. I must be missing something because I can't figure out, no matter how many times I watch either film, what the underlying subtext of the narrative is? Can someone help me, that has seen and thinks they understand 'Sleuth', explain their interpretation of what the hidden subtext might be, between the two characters please?
