1. The Forbidden Kingdom - $20.9 million
Lionsgate's action picture starring venerable martial arts masters Jackie Chan and Jet Li (and newly minted Kung Fu superstar Michael "Who?" Angarano) may not have registered too highly on your own new-release radar. But its surprise #1 finish meant there was indeed an audience looking for a fresh spin on the increasingly hackneyed plots served up by the genre, and who simply couldn't get enough of this touching story of two dads, as deadly fisted as they are in love, trying to raise their troubled teenage son the best way they know how.

2. Forgetting Sarah Marshall - $17.3 million
It outperformed the Apatow Pictures Group's previous two releases, but not even its ubiquitous Sharpie marketing campaign and an unobstructed view of Jason Segel's semi-chubby man-parts were enough to earn Sarah Marshall the kinds of Superbad and Knocked Up numbers responsible for ushering in Hollywood's Golden Age of the Paunchy, Lovelorn, Post-Adolescent Jew. Still, a respectable second-place finish hardly suggests genre-fatigue. Perhaps all that's needed to again crack the $30 mil mark is to up the male-nudity ante, finally conquering Hollywood's long-standing cyclops taboo in a close-up sequence that involves a frantic Seth Rogen bending over to fish his wedding ring out of a shower drain.

3. Prom Night - $9.1 million
Sony's re-envisioning of the 1980 Jamie Lee Curtis slasher dropped 56% and two positions in its second week, but it hopefully performed strongly enough overall to convince the studio to give another Curtis effort from that year—the David Copperfield- and trannie-packed choo-choo classic Terror Train—the remake treatment.

4. 88 Minutes - $6.8 million
We're thrilled to report that Al Pacino's latest effort has inched ahead in the Metacritic tracking from its original score of 2 to a much more respectable 17, though, not surprisingly, it has been stripped of its bronze medal in the Shitty Film-A-Lympics.

5. Nim's Island - $5.65 million
Not even a second-billed Jodie Foster could get parents interested in the goings-on on Nim's Island, where mad scientist Dr. Nim, played by the lovable Abigail Breslin, successfully fused animal and human DNA in her misguided attempts to play God.

• WEEKEND BOX OFFICE April 18-20, 2008 [Box Office Mojo]

WHAT'S NEW: Chockablock with tropical raunch and waaaay more of Jason Segel than you ever wanted to see, Forgetting Sarah Marshall has Variety suggesting that the film's "R" rating could push it down to a opening weekend "in the low- to mid-teens." Not half-bad for a studio comedy budgeted at $30 million, but probably not enough to surpass the PG-13 Jet Li-Jackie Chan action-fantasy The Forbidden Kingdom, which is predicted to top out around $18 million on roughly 3,100 screens. Also opening: Morgan Spurlock's gonzo War-on-Terror doc Where in the World is Osama Bin Laden?; the portentous Uma Thurman-Evan Rachel Wood drama The Life Before Her Eyes; the Ben Stein entry Expelled; and the throwaway MGM thriller Pathology.

THE BIG LOSER: Prom Night stands to drop as much as 70% from last week's No. 1 spot, but really, we're just waiting to see what kind of audience revolt ensues at screenings of 88 Minutes. Already recognized among the decade's most reviled films, the Al Pacino suspenser will likely draw about $30 million in masochistic lookie-loos, with $25 million being returned shortly thereafter in angry box-office mutinies around the country.

THE UNDERDOG: We haven't even seen the Jenna Jameson crossover vehicle Zombie Strippers, but that's no reason for us to withhold our zeal. Plus, let's face it: The world needs a Robert Englund comeback in the worst way.

FOR SHUT-INS: New on the DVD shelf this week are special editions of the essentially interchangable Juno and Alien vs. Predator - Requiem; other titles include the Sidney Lumet drama Before the Devil Knows You're Dead, Ryan Gosling's sex-doll romance Lars and the Real Girl and the long-long-awaited complete fourth season of Melrose Place.

Take a few minutes and call your own shot for the weekend — can male full-frontal knock Jackie Chan out of the multiplex? Are you getting your pitchfork and/or torch ready for 88 Minutes?
