Hover over the Films by year button in the top menu to access a drop-down menu of decades (for example 1900-1909). If you click on these links, you will be taken to an overview page where I briefly summarise the decade in question from the point of view of science fiction films and the social, cultural and political background in which they were made. Hovering over these links in the menu will give you another sub-menu with individual years. Clicking on, for example, the year 1931, will give you a list of all films published in 1931 that I have reviewed.
