“This is a small town, and small towns are supposed to be safe!”
FRIDAY THE 13TH PART IV: THE FINAL CHAPTER made almost as much as its predecessor so – Ah, hell, who are we fooling? Let’s make another one so immediately that it can be released in less than a year!
To restart the series they went to director Danny Steinmann, whose horror experience was THE UNSEEN (1980), and who’d just done SAVAGE STREETS starring Linda Blair. Steinmann gets a writing credit alongside part III co-writer Martin Kitrosser – because they used his early attempt at the part III script that would’ve been about Part II’s Ginny in a mental institution – and newcomer David Cohen, who rewrote that script (and would go on to write and direct HOLLYWOOD ZAP [1986], about “two friends, one searching for his father, the other searching for the ultimate sexual video game competition.”)
FRIDAY THE 13TH: A NEW BEGINNING cold opens with the type of storm the original FRIDAY THE 13TH had to build to. Part IV’s pre-teen Jason-killer Tommy Jarvis (Corey Feldman) is visiting a cemetery (not the same “old cemetery” from the last installment) where there’s a makeshift grave for Jason (who buried him?). Tommy watches as two idiotic, cackling fuckos dig up Jason’s worm-covered, still-masked corpse just for laughs. And then, for some reason (or none at all – you know how these resurrections go) Jason sits up and kills them. (read the rest of this shit…)
HARD ROCK NIGHTMARE is an account of the tragic events that befall the up and coming rock ‘n roll band The Bad Boys when they stay at Jimmy’s grandma’s farm for the weekend. They “gotta get ready for the concert” so at first they practice in their garage with one girlfriend watching. But she accidentally bumps the garage door opener just as three other young female rock ‘n roll aficionados are walking down the sidewalk, so they stand and watch and swoon. But also it attracts a police car and they get shut down.
They’re kind of an unlikely band because there are two dudes with slicked back hair, leather jacket and jeans, others are standard long hair dudes, and a guy with a trenchcoat, and one guy is a Mike Mills looking nerd often wearing a Nike sweatshirt. Like they’re a couple different bands accidentally combined. I’m not sure if all their music is like this, but the song we hear is funny because the chorus is “It’s a nightmare!” but the lyrics are all about wanting to start a band and “work really hard.” The first line is “It started when I got my first guitar at the age of ten…” So the band and “a couple of hot babes” from the sidewalk head out to the farm.
