''The Matrix'' was back on top this weekend with an estimated $12.9 million after taking one week off from the No. 1 spot. But the action film -- which has pulled in a total of $117.4 million -- was the only big success story. While the four-week-old hit dropped just 28 percent from last week, ''Life'' fell 43 percent in its second week, to $11.6 million, sentencing it to second place after only one week at the top. And it was only part of a general plummet: The total box office gross was down 20 percent from last weekend.

Two new releases landed with a resounding thud: The air traffic controller comedy ''Pushing Tin'' crashed into fourth place with $3.6 million, while David Spade's ''Lost & Found'' ended up in the doghouse with a sixth-place $3.1 million. Rounding out the top five were third-place ''Never Been Kissed'' ($6.2 million) and No. 5 ''Analyze This'' ($3.2 million). The only new bright spot came from the Reese Witherspoon high school satire ''Election,'' which opened in New York and L.A. with a whopping $20,000 per-screen average (compared to ''Pushing Tin'''s meager $2,800). Paramount has decided to open ''Election'' wider next weekend -- one week earlier than the studio originally planned -- in hopes of building on the film's early momentum and positive reviews.
