Have you ever forgotten something so badly that you tattooed it on your own skin? This is the realization for Leonard, an amateur sleuth who goes to a city to try and find his wife's murderer. The only downside is that he suffers from short term memory loss every hour or so. An amazing mystery film that showcases Guy Pierce in all the right ways with a non linear story that leaves the viewer with just as much questions as the character. A great mystery film to continue this month and is certain because "certainties, thats the memories you take for granted".
