From Top to Bottom: Beyoncé's Obsessed

The Ali Larter/Beyoncé Knowles catfight thriller Obsessed opened at number 1 this weekend with a $28.5 million take. Calling to mind the "blank-from-hell" thrillers of the '80s and '90s, Obsessed 's "blank" is a temp and wannabe mistress, played by Larter (TV's Heroes ), who, after failing to seduce her coworker, wrecks havoc on his life, Fatal Attraction -style (although this pic's gotten more The Temp -style reviews). Knowles costars as the Anne Archer-esque endangered wife, adding racial overtones and "oh-no-she-didn't" spunk to the proceedings. Despite the fact that Knowles doesn't sing her ubiquitous rendition of "At Last" in the film, the Screen Gems release still manages to deliver a number of effective scares.

The Zac Efron comedy 17 Again slipped to number 2 this weekend, taking in $11.6 million for a two-week total of $39.9 million. Its 50% drop from last week suggests the Warner Bros. body-switching comedy is headed for less-than- Big numbers. Matthew Perry costars as the older version of Efron's character, while the always hilarious Leslie Mann ( Knocked Up, The 40-Year-Old Virgin ) plays his wife. Things get a little awkward for the Mann character when she ends up developing a cougar crush on the Efron version of her hubby. I'm sure she's not alone in having age-inappropriate feelings for the well-coifed teen-beater, but I'll take a Tatum over an Efron any day.

OK, if you don't know Channing Tatum from the 2006 guilty-pleasure dance drama Step Up , trust me, you'll know him by the end of this summer, after his two blockbusters-in-waiting, G.I. Joe and Michael Mann's Public Enemies , are released. Right now, the former Abercrombie and Armani fashion model's not quite a household name, as evidenced by the modest third-place finish and $11.4 million take of his latest film, Fighting . Tatum stars in the Rogue Pictures release as a young counterfeiter introduced to the world of underground (and sometimes shirtless) street fighting by a seasoned scam artist, played by Terrence Howard ( Hustle & Flow, Iron Man ).

The Paramount/Dreamworks drama The Soloist debuted in fourth place with $9.7 million. Robert Downey Jr. stars in the film as a Los Angeles journalist who discovers a schizophrenic musical genius (Jamie Foxx) living on the streets. The Soloist was originally scheduled for release last winter during awards season. So far, results have been less than melodious in the more lighthearted and light-headed spring season.

Disney debuted both its new release label Disneynature and the label's first offering, Earth , this weekend for an $8.5 million take and a fifth-place finish. The filmmakers behind the acclaimed BBC series Planet Earth directed this new nature documentary, which traces the migration paths of four animal families. Apparently, Morgan Freeman was busy, so James Earl Jones provides the sage narration.

In six place, Monsters vs. Aliens frightened moviegoers out of another $8.5 million, bringing its five-week cume to $174.8 million. The Paramount/Dreamworks animated hit features the vocal talents of Will Arnett, Stephen Colbert, John Krasinski, Hugh Laurie, Seth Rogen, Paul Rudd, Kiefer Sutherland, Rainn Wilson, Reese Witherspoon, and Renée Zellweger -- basically, half of Hollywood should receive lifetime residual checks from this thing.

In seventh place, the Universal thriller State of Play entered a state of box office emergency, earning a mere $6.8 million for a dire two-week total of $25 million. That number is especially low considering the fact that, individually, stars Ben Affleck, Russell Crowe, and Rachel McAdams have proven to be viable box office draws. Maybe moviegoers would have preferred seeing the cast in a state of fun, instead of in a probing, adult thriller about journalists investigating political crime.

Hannah Montana: The Movie earned $6.3 million in its third weekend for an eighth-place finish and a $65.5 million cume. Although Hannah may be dying a bit at the box office, its Miley-driven soundtrack counterpart is currently number 1 on the Billboard 200.

In ninth place, Universal's F ast & Furious stalled out a bit with a $6 million take. With a four-week total of $145.2 million, the fourth installment in the hot-rod franchise did finally manage to dethrone 2001's The Fast and the Furious to become the highest-grossing entry in the series (we'll ignore inflation, because that's what Hollywood does when celebrating earnings).

Jason Statham's action sequel Crank: High Voltage landed at the hot bottom of the list this week, earning an un-muscular $2.4 million for an $11.5 million two-week total. I think this Lionsgate franchise is pretty much ovah, unless the next one features Statham transporting something in the nude.

Stay tuned for next week, when we report on the already available-for-illegal-download X-Men Origins: Wolverine, the Matthew McConaughey/Jennifer Garner romcom Ghosts of Girlfriends Past, and the animated epic Battle for Terra.
