The Pointing Finger (1933)

This is one of those cheap and cheerful efforts that you watch if you have an hour to kill and an enthusiasm for early British cinema. The tiny budget really does encumber the flow of the story - a cousin (Leslie Perrins) tries to steal the inheritance of his cousin John Stuart (the legitimate Earl of Rollestone) who appears to have been lost in Africa, by means of some doppelgänger malarkey. Luckily his sister "Lady Mary" (Viola Keats) is on hand to help thwart his evil intentions. It's a daft story, overly convoluted, lit by candlelight with a minimum of technical effort and little acting talent - but it isn't awful and was probably made in a week!
