Austin. Sunday. Miracle Mile. Be there, or be square.

Great news: Miracle Mile, writer-director Steve De Jarnatt's classic 1989 thriller, will be screened at 7:20 pm Sunday at the Alamo Drafthouse Ritz in Austin. But wait, there's more: It's my great pleasure and privilege to announce that I'll be serving as host (or facilitator, or whatever the hell they call it) for an on-stage Q&A with De Jarnatt after the screening.

I am especially geeked about the occasion because... well, this isn't the first time I'll be involved with a public showing of De Jarnatt's devastating flick. Back in 1989, I introduced it as my critic's choice at the WorldFest/Houston International Film Festival (then known simply as the Houston International Film Festival), where it wound up rocking the house and winning best of fest honors. 

A few weeks later, during a Cannes Film Festival reception, I was told by one of the muckety-mucks at Hemdale -- the outfit that had originally bankrolled the film -- that because of the enthusiastic response at the H-Town fest, his company was giving Miracle Mile a wider theatrical release than originally planned. He also said my rave review -- blurbed in all the original advertising and, later, on the homevideo packaging -- was another factor considered when the Hemdale brass made their decision. 

Maybe he was telling me the truth, maybe he was stoking my ego. But consider: De Jarnatt recently thanked me in a Facebook post for being an early supporter of his film. So I can only assume that I played some role, however small, in getting Miracle Mile out into the world. And that makes me very happy.

So what's it all about? As I wrote in my 1989 review:

Miracle Mile is an audacious doomsday thriller with a 20-megaton impact. Deceptively simple and relentlessly gripping, it represents American independent moviemaking at its most exciting and accessible for mainstream audiences. Be prepared to be blown through the back of the theater...

Anthony Edwards (Revenge of the Nerds) and Mare Winningham (St. Elmo’s Fire) are the lead players, and they are exceptionally well-cast. Edwards is excellent as Harry, a soft-spoken, sweet-natured would-be jazz musician who moves to Los Angeles in search of a musical career and, perhaps, romance. Like most newcomers to Los Angeles, he checks out the sights on the Miracle Mile, the long stretch of Wilshire Boulevard that runs from the towering skyscrapers of Century City to the edge of the La Brea Tar Pits. On a museum tour near the pits, Harry meets Julie (Winningham), a lovely waitress who just happens to be fond of jazz. Love blooms, instantly.

Unfortunately, Harry oversleeps, and arrives at the diner where Julie works three hours late for their midnight date. He tries to call her from a pay phone, but she doesn’t respond -- she has taken a sleeping pill, turned on her answering machine, and dozed off. Harry is depressed. Worse, he doesn’t know exactly where Julie lives, so he can’t drop by to apologize.

Then the pay phone rings, and Harry picks up the receiver. On the other end is an anxious young man calling from a missile base somewhere in North Dakota. It’s a wrong number -- the caller was trying to reach his father in another area code, to warn him that World War III is about to begin, that nuclear missiles will likely hit Los Angeles in 70 minutes.

Harry thinks the caller is a practical joker. But then he hears gunshots. And then he hears a stern voice on the line, warning him to “forget everything you’ve just heard, and go back to sleep.” 

This is not a dream. This is not a test. This is an actual alert.

And that is all the detailed plot synopsis you will get from me. Suffice it to say that Harry moves heaven and earth to get to Julie, so she can join him for a last-chance flight to safety. Naturally, several obstacles, and not a few people, get in his way. And even when the lovers are reunited, they have to contend with the panicky mobs who have been tipped off about the approaching apocalypse.

Writer-director Steve De Jarnatt draws you slowly, steadily into his frightfully plausible plot before he yanks you by the lapels and drags you onto a high-velocity roller coaster. Better still, even while he skillfully, even mercilessly, escalates the suspense, he develops a credible, compelling love story. Edwards makes a strong impression as an ordinary man in an extraordinary situation, while Winningham is attractive, persuasive and, particularly in the final scenes, achingly poignant. The supporting players are strong, and the dialogue, often darkly comical, rings true.

Miracle Mile flies economy class, with more emphasis on human drama than special effects, but it never looks or sounds cheap. The first-rate cinematography is by Theo Van de Sande, and the ominous musical score is by Tangerine Dream.

And if all of that is not enough for you, take note: Cherry 2000, De Jarnatt's only other feature, a 1987 sci-fi action-adventure in which a badass Melanie Griffith makes things blow up real good, also will be screened Sunday at the Alamo Drafthouse Ritz. And, yes, De Jarnatt will be answering questions about that one, too.
