What's scarier: an Ivy League brat with a billion dollars and a lot of grudges, or a pair of creepy, demonic little girls? Ask yourself that question as you ponder this weekend's new movie choices.

New and Noteworthy: 'The Social Network'

Starring:Jesse Eisenberg, Justin Timberlake, Andrew Garfield, Rashida Jones
Directed by:David Fincher
What It's About: It's about the founding of Facebook, how it grew from a college dorm-room prank into a global phenomenon -- and a source of bitter, multimillion-dollar lawsuits among its founders. It's also about how a group of Harvard snobs with no social skills created the planet's biggest ongoing party, how creator Mark Zuckerberg (Eisenberg) became the world's youngest billionaire, how a guy who changed the way we use the word "friend" lost all of his own and how the great egalitarian leveling power of the Internet is still trumped by old-school markers of class and privilege.
Why Should You See It? Because Fincher and screenwriter Aaron Sorkin make surprisingly compelling drama out of a story that takes place largely at computer keyboards and lawyers' offices. Because it addresses an up-to-the-minute topic in the form of a classic drama about inspiration, friendship, money and betrayal. Because it's proof Justin Timberlake (as Napster founder Sean Parker) can act. Because it's the biggest surefire Oscar contender so far this year. And because, by Monday morning, all your Facebook friends will be asking each other if they've seen it.

'Let Me In'

Let Me InStarring:Chloë Grace Moretz, Kodi Smit-McPhee, Elias Koteas, Richard Jenkins, Sasha Barrese
Directed by:Matt Reeves
What It's About: Like the 2008 Swedish hit 'Let the Right One In,' this Americanized remake is about a lonely boy ('The Road's' Smit-McPhee) who befriends his new neighbor, a mysterious little girl ('Kick-Ass's' Moretz) who happens to be a bloodthirsty vampire.
Why Should You See It? Advance buzz has it that 'Cloverfield' director Reeves' remake is true to the spirit of the original: haunting and contemplative, not just horrific. In fact, it may be even better than the original.

Staying In This Weekend?

New on DVD This Week
: Okay, 'Iron Man 2' didn't quite measure up to the unexpectedly good 'Iron Man,' but it still had plenty going for it: not just the cocky Robert Downey Jr., but also such upstagers as a villainous Mickey Rourke and a slinky Scarlett Johansson. If you're one of the five people who missed it in theaters, now's you're chance to see it at home. Buy or rent the DVD | More new DVD releases

Movie Homework, Part 1: 'The Social Network' takes place at Harvard, but very little of it was shot there. The deans of America's oldest university seldom allow Hollywood productions on campus, and who could blame them, since the few exceptions they've made have yielded such cringeworthy results as 'Love Story' and 'With Honors'? One of the better movies shot at the 374-year-old campus is 'Good Will Hunting,' which, like the Facebook movie, is about an antisocial young number-crunching prodigy. And like Mark Zuckerberg, star Matt Damon seems to have done fine despite dropping out of Harvard. Buy or rent the DVD

Movie Homework, Part 2: Scary little girls have been popular in horror films for at least the last decade, from 'The Ring' to 'Orphan.' But the mother of all scary little girls is the homicidal blond moppet played by Patty McCormack in 'The Bad Seed' back in 1956, a scary turn that earned the pigtailed 11-year-old an Oscar nomination. Buy or rent the DVD

On My Netflix Queue: The death this week of director Arthur Penn made me want to revisit 1967's 'Bonnie and Clyde,' a movie that broke pretty much every rule of Hollywood storytelling (what with its warped sexuality, extreme violence, amoral heroes, and cathartically bleak ending) and launched a decade-long renaissance in American moviemaking. The movie can still pull the rug out from under you, not least because of the performances of the impossibly beautiful young Faye Dunaway and Warren Beatty.Buy or rent the DVD.
