The very earliest "movies" can be seen in the rise of something of a in-between technological advance in photography and true motion picture cameras: it's called series photography and it's inventor was one Eadweard Muybridge (who was actually born in UK [Kingston-upon-Thames, England] as Edward Muggeridge.)

The first, and most famous of these, is the series of horse photographs dating from 1877 (see plate above). Though photography had been around since the 1820's, the amount of exposure time needed to produce these images was rather encumbering in terms of portability (actually an understatement). As the the 19th century advanced, so did technologies within the photographic world. The reduction of exposure time from a full 15 minutes to 1/100 of a second by the 1870's, made photography a more portable and out door affair; however, it was really the change in photographic plates that made what Muybridge would conceive of as possible. The introduction of gelatin dry plates made outdoor photography a much portable and cheaper affair (the plates before these had been wet silver plates, which didn't travel nearly as well and were much more expensive). The new advances also improved the quality of outdoor photography especially.
