Westworld (1973)

Plot hole: There's a huge, fatal flaw with the whole concept of having guns that cannot fire on human guests as it detects the body heat. Unfortunately it's a stone cold, 100% certainty that with the amount of gunplay going on in Westworld, virtually every day someone is going to be killed by a ricochet. Ricocheting bullets can and do kill people, and any scientist capable of designing guns like the ones they use in Westworld must know that. They aren't using frangible soft rounds like those used by prison guards - the gunfights are all characterised by the sharp, metallic sounds of ricocheting bullets. It's not a matter of legal liability, or the owners protecting themselves from lawsuits - it's a matter of people not paying to stay in a theme park where the chances of dying or sustaining life-changing injuries are are extremely high. Bad press would kill Westworld (and its sister theme parks) stone cold dead within days of the first bodies being brought out, the bodies of people being killed by ricocheting bullets.

John Blane: There's no way to get hurt in here, just enjoy yourself.

Trivia: When Yul Brynner chases Richard Benjamin into the android lab, Benjamin douses Brynner with concentrated hydrochloric acid (attempting to blind the killer android), and Brynner's face sizzles, bubbles and starts melting. The acid effect for this shot was achieved in a decidedly low-tech manner: Pulverized Alka Seltzer antacid tablets were mixed with Yul Brynner's facial makeup; Brynner's face was then doused with water, and the Alka Seltzer fizzed away Brynner's makeup as piped-in stage smoke swirled about his head.
