Clockwise from top: Police Academy, A Nightmare on Elm Street and Private Benjamin.

There’s no waking up from all the 1980s-era remakes being churned out by Hollywood. The latest? A Nightmare on Elm Street, opening Friday with Watchmen’s Jackie Earle Haley as Freddy Krueger. And Freddy’s not alone. Also in the pipeline: Police Academy, Private Benjamin (with Anna Faris in for Goldie Hawn), Fright Night, Red Dawn and Footloose. That’s not counting the now-shooting prequel to John Carpenter’s The Thing or in-development sequels to Ghostbusters, Who Framed Roger Rabbit and Beverly Hills Cop.

All of which begs the question: is there anything Hollywood won’t remake? Well so far Steven Spielberg’s oeuvre of classics — Jaws, Close Encounters of the Third Kind or ET: The Extra-Terrestrial, to name three — is untouched, probably because no one wants to risk the wrath of Hollywood’s most powerful, popular director. And because George Lucas owns Star Wars, it’s up to Lucas himself to sully the memory of his space saga.

On a similar note, many filmmakers, perhaps to prevent others from doing so first, are planning to revisit their Reagan-era hits themselves — as Spielberg did with 2008’s Indiana Jones and the Kingdom of the Crystal Skull.

For instance, Oscar-winner Robert Zemeckis may helm the Roger Rabbit sequel, while Ivan Reitman is circling the third Ghostbusters. And Ridley Scott (Gladiator, Robin Hood) will direct the prequel to his 1979 smash Alien.

BACK IN THE SADDLE: Speaking of iconic 1980s movies, is that era’s biggest star, Harrison Ford, now segueing into the kind of showy supporting roles that revitalized Sean Connery’s career in the late 1980s-early 1990s?

We ask because Ford’s next role is an unspecified part in Cowboys and Aliens from Iron Man director Jon Favreau (if you can’t figure out the plot from the title, we’re not going to help you). But we know Ford isn’t the lead because Daniel Craig has already been cast as the movie’s hero.

YOU SUNK MY BATTLESHIP! Hollywood isn’t done with Paul Gross yet, despite the quick demise of his TV series Eastwick.

Gross, who’ll be onscreen this week in the dryly funny Canadian-made Western Gunless, renewed acquaintances with an old friend, actor-turned-director Peter Berg (Hancock), who hired Gross as a writer on his next project — a $220-million action film based on the game Battleship.

That’s right. Battleship. It’s part of a post-Transformers deal Hasbro swung with Universal to make movies out of its board games and toys (including Clue, Ouija and Stretch Armstrong).

“It’s one of those monster tentpole films,” says Gross, who inherited the Battleship plot (aliens descend and attack by sea) and had to flesh out the characters. “Of course they’d land on water, there’s so much of it,” Gross says, rolling his eyes. “There’s a certain suspension of disbelief you have to get past when you write this stuff.”

Of course, “You sunk my battleship!” stands to be a tagline.

“That was one of the conversations I had with Pete,” Gross says. “He said, ‘Maybe we could kind of go away from the you ‘sunk my battleship’ thing.

“And I said, ‘Y’know what? You gotta go really big with it!’ I wrote this whole scene a gigantic shot of this guy screaming at the alien, ‘You sunk my battleship!’ And I wrote on top of it, ‘Think Michael Bay, Pete.’ ”

Battleship is set to shoot in August with Taylor Kitsch (Friday Night Lights) in the lead.
