"How to Train Your Dragon" is proving hard to slay -- claiming the top box-office spot in its fifth weekend in theaters,

SOARING AGAIN: Hiccup and Toothless in "How to Train Your Dragon" are back on top of the box office after weeks in second and third place.

"How to Train Your Dragon" is proving hard to slay -- claiming the top box-office spot in its fifth weekend in theaters, studio estimates released yesterday show.

The animated film earned $15 million, dropping just 23 percent from last weekend's take.



Jennifer Lopez's "The Back-up Plan" made $12.3 million, while the action comedy "The Losers" opened short of expectations, at $9.6 million.

"We couldn't be more thrilled," said Anne Globe, head of worldwide marketing for DreamWorks Animation SKG, which produced "Dragon."

"The Back-up Plan," Lopez's first screen venture since 2006, opened within industry expectations. The singer/actress stars opposite Alex O'Loughlin.

Released by CBS Corp.'s film division, it was made for $35 million and ruled Friday night -- only to lose the lead as families streamed into matinee showings of "Dragon."
"How to Train Your Dragon" worked its way back into first place at U.S. and Canadian theaters this weekend, Bloomberg reports. "How to Train Your Dragon" debuted as the top movie on March 28 before dropping to third place and then inching its way into second place last weekend.
