“How to Make a Killing” has a similar plot to the 1949 British film “Kind Hearts and Coronets”, black comedy starring Alec Guiness. The plot centers around a poor man who has a number of relatives ahead of him to inherit a fortune. He ends up killing all of them so that he is the sole heir. “How to Make a Killing” follows a similar plot with Glen Powell as the poor relative. He comically bumps off seven relatives without getting caught, but ends up in jail in an ironic way The methods he uses are clever and funny. Of course there are a couple of romances and the ending is not expected, This is light entertainment. Powell is enjoyable and the supporting cast is quite good. Worth seeing.
