As many predicted, 'X-Men: First Class' easily took the top spot at the box office this weekend.

Still, the Marvel reboot, which traced the beginnings of the 'X-Men' characters, managed to fall well below expectations, taking in just $56.0 million. To put things in perspective: That's the lowest debut by an 'X-Men' movie since the franchise launched in 2000, with $54.5 million.

Also disappointing this weekend was last weekend's champion, 'The Hangover Part II,' which dropped a drastic 62 percent, to just $32.4 million. On the plus side: The sequel to the popular 2009 comedy has raked in $186.9 million over 11 days, which should only fuel speculation about a possible third movie in the franchise.

Meanwhile, 'Kung Fu Panda 2' and 'Pirates of the Caribbean: On Stranger Tides' also took serious dips, earning $24.3 million and $18.0 million, respectively.

'Bridesmaids' rounded out the top five with a steady $12.1 million, pushing it past the $100 million mark. So, not all bad news.
