The new vampire thriller “30 Days of Night”' took a commanding early lead at the North American box office, while the serious dramas 'Gone Baby Gone,' 'Rendition' and 'Things We Lost in the Fire' were on track for disastrous debuts.

'30 Days of Night,' which revolves around a vampire invasion of an Alaskan town shrouded in 24-hour darkness, earned about $6.25 million on its first day of business, according to data issued by box office tracking firm Box Office Mojo (boxofficemojo.com).

The film's distributor, Columbia Pictures, predicted the film would end up with a three-day tally of about $15 million, in line with industry forecasts before it opened. Columbia is a unit of Sony.   

Incumbent champ, 'Why Did I Get Married?' was second with about $3.4 million. Based on its trajectory last weekend, writer/director/actor Tyler Perry's romantic comedy-drama should tally about $9.5 million in its second round. The film was released by Lionsgate, a unit of Lions Gate Entertainment.

Studio estimates for the weekend will be issued on Sunday morning, followed by final data on Monday.

As for the other new releases, Box Office Mojo estimated Miramax Films' crime thriller 'Gone Baby Gone' opened at No 6 with $1.9 million, New Line Cinema's suspense drama 'Rendition' at No 9 with $1.4 million, and Paramount-DreamWorks' domestic tragedy 'Things We Lost in the Fire' at No 15 with $505,000.

Fox sports movie spoof 'The Comebacks' beat them all, coming in at No 5 with $2.1 million, although it played on more screens.

Industry pundits had expected most of the five new releases to reach $10 million for the weekend -- a figure that only '30 Days of Night' is likely to reach.

But a DreamWorks spokesman said the studio had been hoping only for a $3 million to $4 million weekend for 'Things We Lost in the Fire.' Based on Friday's haul, he expected the Benicio Del Toro-Halle Berry vehicle would come in at $1.6 million to $1.7 million. While obviously a disappointment, he noted that it cost a modest $16 million to make, and that the Oscar-winning stars got great reviews.

In the end, it seemed moviegoers had a limited appetite for the onslaught of serious dramas: Del Toro plays a heroin addict and Berry a newly widowed mother, while 'Gone Baby Gone' centers on kidnapped children, and 'Rendition' on terrorism.

'Gone Baby Gone' marks the feature-directing debut of Ben Affleck, who cast his younger brother Casey in the lead role as a Boston private detective. 'Rendition' stars Reese Witherspoon as a woman whose husband is kidnapped and tortured by the CIA.
