There's still some fire left in 'How to Train Your Dragon,' The five-week old movie earned an estimated $15 million this weekend, enough to reclaim the box office throne it last held a month ago and to edge closer to the $200 million mark (it's earned $178 million so far). 'Dragon' easily defeated the three new movies that opened this session, all of which debuted with so-so numbers, leading to the weakest weekend at the box office so far this year.

'Dragon,' a family film still riding high on its positive word-of-mouth, 3-D-enhanced grosses, and hefty theater count, had nearly taken the top spot last week against newcomer 'Kick-Ass.' This week, it dropped a mere 24 percent and remained the clear front-runner, with 'The Back-Up Plan,' Jennifer Lopez's much-heralded return to mainstream romantic comedy, settling for second place with a modest $12.25 million opening. Lopez was up against the still-strong rom-com 'Date Night,' which slid just 37 percent in its third week for a $10.6 million take and a total so far of $63.5 million.

Despite a colorful and clever marketing campaign, new action movie 'The Losers' opened in fourth place with just $9.6 million. Still, that was enough to make a loser of action rival 'Kick-Ass,' which plunged 52 percent in its second week, landing at No. 5 with $9.5 million (two-week total: $34.9 million).

The week's other new movie was Disney's nature documentary 'Oceans,' which got a head start opening on Thursday (which was Earth Day). 'Oceans' opened at No. 8 with $6 million ($8.5 million including Thursday's take), strong for a documentary but below the $8.8 million opening weekend Disney's similar 'Earth' enjoyed on Earth Day weekend last year. ('Earth' debuted on a Wednesday; including its first weekend, its five-day opening totaled $14.5 million.)

Total Top 10 box office struggled to hit the $100 million mark this weekend. Perhaps the marketplace is waiting for a resurgent Freddy Krueger to awaken it from its slumber with this coming weekend's 'Nightmare on Elm Street' reboot, or for the beginning of summer movie season the following week with 'Iron Man 2.'
