Hollywood has pretty much said farewell to summer, sending off its last unloved titles into the wasteland of late August releases.

Now it’s time to think about the fall films - the ones that will greet schoolkids on weekend breaks and occasionally lure the grownups back into the multiplexes.

Of course, if you have been in a theater recently, you have already heard about some of these movies from their trailers. Here is a rundown of some of the more interesting trailers for this fall’s movies, with a grade for how well the trailer whets our appetite for the movie (on a 1-to-10 scale):

l “Just Like Heaven” (opens Sept. 16) - Young doctor Reese Witherspoon gets in a car wreck, and her spirit bedevils the poor guy (Mark Ruffalo) who takes over her apartment. The trailer for this “Ghost”-lite romantic comedy dwells too much on the Witherspoon character’s nonexistent social life. On the plus side, it shows glimpses of what looks to be a scene-stealing turn by Jon Heder - the artist formerly known as Napoleon Dynamite - as a dude-speaking psychic. Anticipation factor: 7.

l “Serenity” (opens Sept. 30) - This is the big-screen follow-up to “Buffy” creator Joss Whedon’s short-lived (but cultishly beloved) science-fiction series “Firefly” - and through the snazzily cut action scenes you get a good feeling for Whedon’s trademarks, deadpan humor and butt-kicking females. Anticipation factor: 8.

l “Everything Is Illuminated” (opens in September) - Can you wrap your head around the two ideas “screwball comedy” and “Holocaust story”? If you can, you can have a job in Warner Bros. marketing department, replacing whoever tried and failed in getting those ideas across for director Liev Schreiber’s adapation of the Jonathan Safran Foer novel. If you get the job, promise me one thing: no polka music. Anticipation factor: 3.

l “Jarhead” (opens Nov. 4) - Here’s another strange juxtaposition: Marines training for the first Gulf War, to the tune of Bobby McFerrin’s “Don’t Worry, Be Happy.” But this one works in playing up the absurdist nature of war coming in director Sam Mendes’ drama. Anticipation factor: 8.

l “The Exorcism of Emily Rose” (opens Sept. 9) - Creepy horror shocks, par for the course. But what’s truly shocking in this trailer is seeing prestigious actors like Laura Linney, Tom Wilkinson and Campbell Scott. Did somebody lose a bet? Anticipation factor. 4.

l “Shopgirl” (opens Oct. 21) - Claire Danes is the title character, a department-store clerk faced with a romantic choice: the cute poor guy (Jason Schwartzman) or the rich, cultured, older guy (Steve Martin, who adapted the screenplay from his own novella). Seeing Martin in serious mode is the most intriguing thing in the trailer. Anticipation factor: 6.

l “The Fog” (opens Oct. 14) - Oooh, how scary can you make a low-flying cloudbank? Not scary enough, if the trailer (for a remake of a John Carpenter thriller) is any indication. Anticipation factor: 1.

l “Yours, Mine and Ours” (opens Nov. 23) - If you have any respect for Dennis Quaid, you’re likely to be turned off seeing him go through the slapstick ringer in this “Cheaper by the Dozen-and-a-Half” retread (actually a remake of a 1968 Henry Fonda-Lucille Ball comedy) about two people (Quaid and Rene Russo) who marry and combine their 18 kids into a family. Anticipation factor: 2.

l “Oliver Twist” (opens Sept. 30) - Stately production design, lush period details, British accents - I’m getting sleepy just looking at it. But along comes Ben Kingsley, hamming it up under a stringy hairpiece as Fagin, so it may be worth a look. Anticipation factor: 4.

l “Fun With Dick and Jane” (opens in December) - Oh, heavens, another remake (this one of a Jane Fonda/George Segal comedy). But seeing Jim Carrey and Téa Leoni as rich suburbanites who are actually armed robbers looks hilarious. Anticipation factor: 6.

l “Proof” (opens in September) - The trailer for this long-delayed adaptation of David Auburn’s play highlights one thing: the reunion of Gwyneth Paltrow and John Madden, the star and director of “Shakespeare In Love.” Beyond that, the story - with Paltrow as the daughter of a brilliant but erratic mathematician (Anthony Hopkins) - also promises Oscar-caliber drama and the always-welcome presence of Hope Davis. Anticipation factor: 7.
