We've got new posters from a trio of films for you today, varied enough that there should be something to suit all tastes.

• A chilly poster from the vampire thriller Let Me In
• A cartooned one-sheet for Sundance entry Sympathy for Delicious
• Very Jaws-ian French artwork for the fishy horror flick Piranha 3D

Hit the jump to check out the posters.

Here's the synopsis for Let Me In:

An alienated 12-year-old boy befriends a mysterious young newcomer in his small New Mexico town, and discovers an unconventional path to adulthood in Let Me In, a haunting and provocative thriller written and directed by filmmaker Matt Reeves (Cloverfield).

Twelve-year old Owen (Kodi Smit-McPhee) is viciously bullied by his classmates and neglected by his divorcing parents. Achingly lonely, Owen spends his days plotting revenge on his middle school tormentors and his evenings spying on the other inhabitants of his apartment complex. His only friend is his new neighbor Abby (Chloe Moretz), an eerily self-possessed young girl who lives next door with her silent father (Oscar®nominee Richard Jenkins). A frail, troubled child about Owens’s age, Abby emerges from her heavily curtained apartment only at night and always barefoot, seemingly immune to the bitter winter elements. Recognizing a fellow outcast, Owen opens up to her and before long, the two have formed a unique bond.

When a string of grisly murders puts the town on high alert, Abby’s father disappears, and the terrified girl is left to fend for herself. Still, she repeatedly rebuffs Owen’s efforts to help her and her increasingly bizarre behavior leads the imaginative Owen to suspect she’s hiding an unthinkable secret.

The gifted cast of Let Me In takes audiences straight to the troubled heart of adolescent longing and loneliness in an astonishing coming-of-age story based on the best-selling Swedish novel Lat den Ratte Komma In (Let the Right One In) by John Ajvide Lindqvist, and the highly-acclaimed film of the same name.

This works for me as a teaser poster: the blood-stained "me" is a nice touch.  And hey, if you dig it, you've got two different aspect ratios to choose from.

Let Me In hits theaters on October 1, 2010.  Via Empire:

Here's the synopsis for Sympathy for Delicious:

Recently paralyzed DJ “Delicious” Dean battles the mean streets of Los Angeles, struggling to survive in his wheelchair. Yearning to walk again, and fighting to spark the ashes that were once his career, Dean turns to the dubious world of faith healing and gets much more than he bargained for. Lured by easy money and the heat of fame, Dean sells out to an unstable rock band, stomping the dreams of so many who see him as their only hope. World-famous DJ “Delicious” must now tackle his own worst demon-himself-if he is ever to conquer his “handicap” and find true healing.

Written by and starring Christopher Thornton in a gripping performance as the fiercely determined deejay, Sympathy for Delicious is a wildly original story. Mark Ruffalo makes an auspicious directorial debut with a gritty, yet fervent, take on the search for meaning amidst tragedy and the redemptive power that is compassion.

The animated look screams "I just came from Sundance!"  Not necessarily a bad thing.  The design throws a lot on the page, but keeps the background from being too busy with the washed-out effect.

Here's the synopsis for Piranha 3D:

From director Alexandre Aja (The Hills Have Eyes) comes the new action thriller PIRANHA 3D.  Every year the population of sleepy Lake Victoria explodes from 5,000 to 50,000 for Spring Break; a riot of sun and drunken fun. But this year, there’s something more to worry about than hangovers and complaints from local old timers; a new type of terror is about to be cut loose on Lake Victoria.  After a sudden underwater tremor sets free scores of the prehistoric man-eating fish, an unlikely group of strangers must band together to stop themselves from becoming fish food for the area’s new razor-toothed residents. The films stars Jessica Szohr (Gossip Girl), Steven R. McQueen (The Vampire Diaries), Elisabeth Shue, Jerry O’Connell, Ving Rhames, Richard Dreyfuss Adam Scott and Christopher Lloyd.

Gotta love that the studio isn't shying away from the exploitative nature of the film.  The format of the tagline ("Sea. Sex. And... Blood.") reminds me of a less eloquent version of "They're young.  They're in love.  And they kill people."  Of course, this French poster is more influenced by Jaws than Bonnie and Clyde.

Piranha 3D is slated for release on August 20, 2010.  Via Ecranlarge:
