Superhero action comedy Kick-Ass won a tight contest at the North American box-office this weekend,edging out How To Train Your Dragon and reversing the order from early estimates,according to final data released recently. It was the second photo-finish in a row in the coveted race for the No.1 spot. Kick-Ass made $19.83 million at U.S. and Canada box-offices,compared to an earlier estimate released on Sunday of $19.75 million. Dragon made $19.63 million,but the previous estimate put the figure at $20 million. Kick-Ass,a movie about scrappy and self-made superheroes,is from Lions Gate Entertainment Corp and Dragon,a film about a teenage Viking,who domesticates a dragon,was made by DreamWorks Animation SKG Inc. Last week,early estimates showed that comedy Date Night had beaten action film Clash Of The Titans at box-offices,but the next days final figures put Clash at No. 1.Early box-office figures,which are released,can differ from the final tally because studios estimate ticket sales for Sunday based on returns for Friday and Saturday.
