Even with a film that was not even screened for critics coming in at No. 1, the box office's hot streak continued uninterrupted over the weekend -- as overall gross was projected to be about $112 million, 24 percent ahead of the comparable weekend a year ago, according to Media by Numbers. "We have never been in this strong a position heading into the summer season, ever," Media by Numbers President Paul Dergarabedian told the Associated Press. The summer season kicks off next weekend with 20th Century Fox's X-Men Origins Wolverine , which has received much positive buzz, possibly intensified by the online release of a pirated workprint late last month. Also opening is Ghosts of Girlfriends Past , which has also been tracking well. The following weekend brings the return of Star Trek. Still, it seemed like summer last weekend as the Beyoncé Knowles/Idris Elba thriller Obsessed , which reportedly cost $20 million to make, opened with a whopping $28.5 million in ticket sales, or about $11,300 per theater. But perhaps even more surprising was the strong debut for the nature documentary Earth. Playing on 1,804 screens, the Disney release took in $8.55 million -- the highest weekend gross ever for a nature documentary and the third highest for any sort of documentary. It has earned $14.2 million since its opening on Wednesday, Earth Day. Meanwhile, last weekend's champ, 17 Again and Universal's new Fighting were in a close race for second place, with early estimates giving the Zac Efron starrer a slight edge -- $11.66 million to $11.44 million for Fighting. Coming in fourth was the well-reviewed drama The Soloist , starring Robert Downey Jr. and Jamie Foxx, with $9.71 million.

The top ten films for the weekend, according to studio estimates compiled by Media by Numbers 1. Obsessed, $28.5 million; 2. 17 Again, $11.7 million; 3. Fighting, $11.4 million; 4. The Soloist , $9.7 million; 5. Earth , $8.6 million; 6. Monsters vs. Alien s, $8.5 million; 7. State of Play, $6.9 million; 8. Hannah Montana The Movie , $6.4 million; 9 .
