THIS WEEKEND From the dark of night, New Line's vampire action film Blade drove a stake through the hearts of the competition by opening at number one with an estimated $17M over the Friday-to-Sunday period. Its powerful opening put an end to Saving Private Ryan's four-week reign atop the box office charts. Sinking its teeth into 2,322 theaters, Blade, starring Wesley Snipes, sliced up a bloody $7,321 average per coffin. Based on the Marvel Comics character, Blade is the story of a half-vampire half-human hero who seeks revenge on his enemy Deacon Frost, played by Stephen Dorff.

If the estimate holds, Blade will give Snipes the best opening weekend of his career edging out the $16.9M debut of U.S. Marshals from earlier this year. The actor has not had a number one film in nearly three years when To Wong Foo, Thanks For Everything! Julie Newmar spent two weeks at the top in September of 1995 . For New Line Cinema, Blade gave the distributor its ninth biggest opening ever. With a reported budget of $45M, Blade had a strong launch considering the R-rated picture was a top choice among teenage boys. New Line has a good history of marketing martial arts and comic pictures to this demographic group. In August 1995, Mortal Kombat exploded on the scene with $23.3M; last August Spawn opened with an impressive $21.2M; and last November New Line hit number one again with Mortal Kombat: Annihilation which opened with $16.8M.

Slipping a notch to second place was Steven Spielberg's gut-wrenching war drama Saving Private Ryan with an estimated $10.1M in its fifth attack. Off only 23%, the critically-acclaimed motion picture has pushed its total to $142.7M making it the eighth highest-grossing film for the Oscar-winning director. Ryan has also become the second biggest release of the year, passing Deep Impact and Godzilla, and trails only Armageddon. Given the current box office trajectories of the two summer films, and the light competition in the weeks ahead, both Ryan and Armageddon should be able to reach the $190M area creating a tense battle for the summer box office crown.

Another overachiever was found in third place. Fox's runaway hit comedy There's Something About Mary grossed an estimated $7.9M over the weekend and crossed the $100M mark on Saturday, its 39th day of release. Down a scant 11%, Mary's legs show no sign of slowing as the Farrelly Brothers hit moved up a notch from last weekend and has thus far zipped up $104.2M without ever reaching the number one or number two spots. Once again having the lowest decline in the top ten, Mary became the ninth release of the year to cross the blockbuster threshold. Adding in movies released in December, that brings the overall total of films hitting that milestone during the calendar year to thirteen. The popularity of this romantic comedy, which stars Cameron Diaz, Ben Stiller, and Matt Dillon, has surprised most industry observers and has given its studio one of the most profitable titles of 1998. The remarkable staying power of Mary has made it the only summer movie to spend six consecutive weeks in the top five. If it continues to perform this well into the autumn months, Mary could flirt with $150M in domestic ticket sales.

Another Fox release took fourth as How Stella Got Her Groove Back finished the frame with $6.6M, according to estimates, pushing its ten-day cume to an amorous $22.3M. The Angela Bassett romantic drama declined 42% in its sophomore weekend but still enjoyed the second-best per-theater average in the top ten. By comparison, second weekend drops for other recent dramas aimed at African-American women have included 25% for last year's Soul Food, 6% for 1995's Waiting to Exhale (though that compares two four-day holiday frames), and 57% for Poetic Justice from the summer of 1993. Stella should groove her way to about $35-40M.

Rounding out the top five was the Brian De Palma thriller Snake Eyes, starring Nicolas Cage, with an estimated $5.1M in its third roll of the dice. Down 41%, the Paramount conspiracy film has grossed $40.6M to date and looks headed for a final tally of around $55M.

Opening in sixth with an estimated $4.7M was the dark comedy Dead Man on Campus also from Paramount. With heavy promotion on MTV, the comedy about two failing college students who try to make their roommate commit suicide so they can get straight A's debuted in 1,797 classrooms with a $2,615 average. With no big-name stars, Dead Man should pick up some modest business in the next two weeks before its target audience heads back to school.

The Drew Barrymore fairy tale film Ever After has proven to be a solid hit with strong midweek business and small weekly declines. Taking in another $4.5M, according to estimates, the Fox fantasy picture is running 18% ahead of that other ancient literature remake aimed at teens - Romeo And Juliet. That 1996 update, also from Fox, starred Leonardo Dicaprio and Claire Danes and ended up grossing $46.4M. Ever After seems destined for a charming final total of approximately $65M.

Sony's new release Dance With Me was tied for seventh with an estimated $4.5M. Debuting in 1,467 ballrooms, the Vanessa L. Williams picture averaged a decent $3,067 per location. Ninth place was claimed by Disney's The Parent Trap with an estimated $3.8M. The family film should hit $60-65M by the end of its run. Halloween: H20 placed tenth with an estimated $3.7M, tumbling 56%. With a moderate-sized budget of $17M, this horror sequel looks to slash up about $55M overall.

Warner Bros. saw two disastrous performances over the weekend from its offerings. First, the expensive, yet critically-panned adventure film The Avengers needed saving from all the negative buzz that surrounded it. The spy film plunged 66% and disappeared from the top ten after just one week with an estimated $3.55M take which lifted its ten-day gross to just $18M. Look for a final domestic tally of about $25M for this $60M-budgeted film. The new release from Warners this weekend, the spoof comedy Wrongfully Accused starring Leslie Nielsen, opened poorly with an estimated $3.4M. The studio backed the film with lots of support including a launch in 2,062 theaters (very wide for a late summer freshman) and a substantial advertising campaign. Unfortunately, moviegoers were not amused as the comedy averaged a pitiful $1,649 per site.

The world's most dominant motion picture, Titanic, netted an estimated $570,000 in domestic ticket sales over the Friday-to-Sunday period pushing its record-breaking cumulative total to $599,687,000. For the first time in 36 weeks, the Oscar-winning film dropped out of the Top 20.
