Its 1973... and in the future people of course wear 70s clothes. The cgi is prehistoric, but groundbreaking. Yul brynner plays a version of the terminator over a decade earlier. The director had his theme park idea which was revisited 20 yrs later with jurassic park. With far greater cgi. Its not the most exciting film ever, but kinda fun. The remake never happened but a tv series which ive not even seen was made, many, many years later. Young viewers of that series would find the original ancient. Yul does a good job of playing a robot. Is this a warning about the dangers of technology? Maybe.. i cant imagine its sequel futureworld would be as good..
