Movie box office numbers again too close to call

It's another photo finish at the weekend box office, with the No. 1 spot too close to call between the animated adventure "How to Train Your Dragon" and the superhero comedy "Kick-Ass."

With just $250,000 separating them, either movie could end up at No. 1 when studios release final numbers today.

Last weekend, 20th Century Fox's comedy "Date Night" led the Warner Bros. action tale "Clash of the Titans" by about the same amount based on estimates. But "Clash of the Titans" came out on top by $1.4 million when final numbers were reported.

"I've never seen two weeks in a row like this where the top movies could easily flip-flop," said Paul Dergarabedian, box-office analyst for Hollywood.com.
