The 1918 version of TARZAN OF THE APES came out just six years after the Edgar Rice Burroughs novel debuted. Seen today, it stands up pretty well, feeling obviously dated but at the same time sticking close to the plot of the original novel, closer than some adaptations that have come since. All of the correct plot ingredients are present and correct and if it's not as lavishly mounted as later instalments, well that's understandable. The interaction with chimps and the like are handled particularly well, and overall despite the creakiness this has a feeling of authenticity.
