The new Ben Affleck movie, “Argo,” begins in November, 1979, with the storming of the American Embassy in Tehran. A crowd breaks into the compound, taking more than fifty Americans hostage. Six escape through the back of the building and take refuge in the residence of the Canadian Ambassador. How can they be spirited out of the country, or, as the jargon puts it, exfiltrated? Back in Washington, the task falls to a C.I.A. staffer named Tony Mendez (played by Affleck), from the Office of Technical Services. Various plans have been mooted, the most credible being that the hostages could make it to the border, hundreds of miles away, on bikes. Mendez, however, has an even better idea. Well, not a better one, but a more ridiculous one: how about making a movie?

Enter John Chambers (John Goodman), a prosthetics guru whose work on simian features, for “Planet of the Apes,” earned him an Academy Award, in 1969, and whose talents the Agency has called on in the past. Mendez goes to Hollywood and asks Chambers to devise a nonexistent film: find a script that requires a Middle Eastern setting, and build up a simulacrum of a genuine production. Posters, storyboards, costumes, read-throughs, buzz in the trade papers: everything will help. Mendez, posing as an associate producer, will fly to Iran, issue false identities to the six Americans, claim that they are scouting locations for a Canadian science-fiction movie, and then fly them out.

Four things should be said about this pipe dream. One, it went ahead; two, it worked; three, it wasn’t declassified until 1997; and four, it makes for a good movie, and further proof that we were wrong about Ben Affleck. Few of us, watching “Armageddon” and “Pearl Harbor,” could see a way out, or back, for an actor so utterly at the mercy of his own jawline. Did he flinch at a future composed of all-American strivers, each more earnest than the last, or had he always been nipped by the directing bug? Whatever the case, Affleck was suddenly there with “Gone Baby Gone” (2007), which was more roughened by energies and doubts than all his performances combined. He took the precaution of recruiting actors more formidable than himself—Morgan Freeman and Ed Harris—to boost his endeavors, and that habit remains. “Argo” has Victor Garber as the Canadian Ambassador, Bryan Cranston as Mendez’s superior, and, most enjoyable of all, Alan Arkin as Lester Siegel, a producer so scornfully amused by Mendez’s request that he has no option but to obey it. He does have one proviso. “If I’m doing a fake movie, it’s going to be a fake hit,” he says.

The fake they decide upon is entitled “Argo,” made by a bogus company called Studio Six, and lovingly described by Chambers as “a twenty-million-dollar ‘Star Wars’ ripoff.” I can’t be the only person who ardently wishes that he and Siegel had gone ahead and shot it. Affleck has a lot of fun, perhaps an ounce too much, with the daftness of the film industry; when Mendez, thinking ahead to the hostages’ cover stories, asks whether you can be taught to direct movies in a day, Chambers replies, “You can teach a rhesus monkey to be a director in a day.” No one is more skilled than Goodman, with his faintly bullying geniality, at dishing up lines like that, but must we buy his character’s implication that Hollywood is just another planet of the apes? Is it good for mendacity, and nothing else?

This matters because “Argo” is, in part, a battle of the textures. When it comes to period detail, Affleck seems to take his cue from Mendez, who worked for the Graphics and Authentication Division of the O.T.S.; just look at the typography of the opening credits, with its bulbous seventies curves. Affleck’s beard and hair style suggest someone who moonlighted from the intelligence services to pose for “The Joy of Sex,” and, as you study the fashions of the era, you have to ask whether the Ayatollah’s fury was provoked by U.S. support for the Shah or, more simply, by the width of Western shirt collars. Everything about the Tehran sequences, in fact, is a rebuke to style. The camera work is anxious and twitching, with a grainy surface to match. Here, we gather, is the real thing: life hemming us in, like a mob.

Then comes the climax. If you visit the C.I.A. Web site, you can read Mendez’s account of events in January, 1980. “As smooth as silk,” he calls the hostages’ passage through the airport, whereas Affleck, chopping up the action and spinning it out, insures that no nails remain unchewed. This is absolutely his right as a teller of tales, and “Argo” never claims to be a documentary. It struck me as a bit rich, however, to make such sport of Hollywood deceitfulness and then to round off your movie with an expert helping of white lies, piling on car chases that never occurred. As for the aftermath, it goes on forever. We get hurrahs for Canadian-American relations; a shot of Mendez hugging his wife, from whom he has been estranged, with the Stars and Stripes fluttering behind; images of the actual hostages, presumably for any skeptics who still find the film implausible; and, finally, a voice-over from Jimmy Carter, lauding the efforts of those involved. All this is, frankly, uncool—a pity, because the rest of “Argo” feels clever, taut, and restrained. Why not close with the perfect coda that Mendez himself supplied? “By the time Studio Six folded several weeks after the rescue, we had received twenty-six scripts,” he wrote. “One was from Steven Spielberg.”

At the start of “Sinister,” Ellison (Ethan Hawke) and his family arrive at their new house. “I had to move here. The new story I’m writing is here,” he explains. Hang on, is he proposing this as a basic principle of literary composition? If so, C. S. Lewis must have really stacked up the air miles on the red-eye from North Oxford to Narnia. Ellison’s excuse is that he writes true crime—that shapeless and often shameless genre which is to good crime fiction what pornography is to romance. His latest project—“This could be my ‘In Cold Blood,’ ” he says—concerns a family that was hanged from a tree outside the very house where Ellison now dwells, although somehow he has failed to inform his wife, Tracy (Juliet Rylance), of this cheerful fact. Up in the attic, he stumbles on a clue: a boxful of old Super-8 films, plus, helpfully, a projector on which to show them. Switching it on, he finds himself watching scenes not just of the hanging but of other multiple murders from the past. Who made the film? Or, rather, WHO MADE THE FILM?, as Ellison writes on his notepad. The director of “Sinister” is Scott Derrickson, who co-wrote the script with C. Robert Cargill, and we can but pray that they move on to a new bio-pic of Melville. Imagine his questions: ONE LEG ONLY? and WHY A WHALE?

The insertion of found footage into horror flicks is now so common as to be almost compulsory, like the use of vomiting in mainstream comedies. What a golden age we inhabit. Ellison, peering at the clips, spies a masked figure known as Mr. Boogie; though that sounds like a bad compilation album from 1975, it refers to a mythological thief of souls, thus plunging the film into the lair of the unnatural. Nothing wrong with that—irrational terrors beset another writer, and his long-suffering family, in “The Shining.” But Kubrick had the common sense to keep the lights on in the Overlook Hotel, and the wit to infuse a simple, carpeted corridor with unease, whereas Derrickson is playing with loaded dice. How can you hope, or presume, to crank up our dread of the inhuman when, from the start, you refuse to play by regular human rules? Throughout “Sinister,” the rooms remain darker than crypts, whether at breakfast or dinnertime, and the sound design causes everything in the house to moan and groan in consort with the hero’s worrisome quest. I still can’t decide what creaks the most: the floors, the doors, the walls, the dialogue, the acting, or the fatal boughs outside.

None of this is fair to Ethan Hawke. From “Dead Poets Society” to “Reality Bites” and “Before Sunrise” to his modern-day “Hamlet,” where he soliloquized on a video display, Hawke was the standard-bearer of the adolescent temper, as it wrestled its way into adulthood. The gauntness, the waves of intensity, the smarting humor: they all made sense, as if his duty, wherever he trod, were to spread a little Hamletry. As Ellison, he looks unhappy and lost, not because some smirking demon wants to joint him like a chicken and drag him to Hell, which can happen to anyone in this kind of film, but because the prison of middle age, dank with fatherhood and money troubles, is no place for a prince, or for a kid who once dreamed of living like one. “Sinister” is a joyless ride, and its frights are too contrived to be surprising, yet somewhere, stashed in the attic, is a much less foolish film with Hawke at its heart. The only problem is, WHO WILL MAKE THE FILM? ♦
