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.

Arrivals Announcer: In trailer: Nothing can go wrong... go wrong... go wrong.

Trivia: Yul Brynner, whose Man In Black character was made famous in earlier American western movies, agreed to reprise the character in Westworld for only $75,000, because he sorely needed the money.
