The Kevin Hart, Ice Cube police comedy "Ride Along" cruised to the top of the box office again, taking in $21.2 million in its second weekend.
On the football-free weekend, no new challenger emerged at the multiplexes. The week's lone new wide release, the monster thriller "I, Frankenstein," flopped. It opened with just $8.3 million according to studio estimates Sunday.
"Ride Along" was followed by the Navy SEAL drama "Lone Survivor." It earned $12.6 million in its fifth week, giving it a cumulative total of $93.6 million.
In third was the animated squirrel comedy "The Nut Job," which made $12.3 million in its second week.
