biggest "Cassandras" in cinema history

Ok, to be fair, most of these are in horror or summer action/disaster films, and occasionally cop films.

only rule is that any movie featuring actual Cassandra is disallowed.

I nominate

Dr Loomis

Halloween

nobody ever fuckin' believes him

but damn if he knows the body count Michael will wreak, right down to what he's feeling.

also...

John McClane in Die Hard 2

Denis Franz literally has to be faux-shot with a machine gun to realize John's telling the truth

don't stop.

keep it goin

I'm just glad to see that you are acknowledging that part of being a 'Cassandra' is that your warnings of approaching calamity, though ignored or not believed, are entirely correct, which is not at all like a 'Boy Who Cries Wolf' or a 'Chicken Little'.
