Scream (1996)

In Wes Craven's horror/slasher film spoof:

• the opening 12-minute prologue scene in which all-American, sweatered girl Casey Becker (Drew Barrymore in a very short cameo) was alone preparing pop-corn to watch a video when she received an initially playful phone call (she was asked "What's your favorite scary movie?" - and she replied Halloween)
• the repeated terrifying calls turned obscene, threatening and ugly; when she demanded to know what the caller wanted, he simply replied: "To see your insides" - and she ended up slaughtered and hanging in the front yard
• the wise words about how to avoid being murdered by the knowledgeable video geek Randy Meeks (Jamie Kennedy): "You can never have sex...you can never drink or do drugs...and number three: never, ever, ever under any circumstances say, 'I'll be right back'"
