Sherlock Holmes II (1908), part of a Danish silent series, is regarded to be the very first full-length ‘sequel’ movie ever in the history of cinema. Given most silent films of the era are considered to be ‘lost’, it is quite difficult to know with absolute certainty, but there seems to be at most one or two ‘sequels’ each year since then. ‘The Fall of a nation’ in 1916 is often touted to be the first Hollywood sequel. They wouldn’t really catch on until the 1970s and 80s when movies like Superman and Godzilla proved to be very profitable for franchising. Today one can barely find a movie that is not a sequel, remake, reboot or spin-off of something else.
