LOS ANGELES (March 24, 2013)--The caveman comedy "The Croods" opened at No. 1 with an estimated $44.7 million this weekend.
The 3-D adventure from DreamWorks Animation and 20th Century Fox features a voice cast that includes Nicolas Cage, Emma Stone and Catherine Keener, who play a prehistoric family encountering danger and strange new creatures when they're forced to find a new cave.
Opening strongly in second place with $30.5 million was "Olympus Has Fallen," an action thriller in which North Korean terrorists take over the White House.
Gerard Butler leads an all-star cast that includes Aaron Eckhart as the president, Morgan Freeman and Angela Bassett.
The opening far exceeded distributor FilmDistrict's expectations, which were in the under-$20 million range.
