Secretariat earned $18 million in its first week, far short of Seabiscuit's $31.6 million, and it sold less than half as many tickets. Still, Secretariat easily outperformed other horse-centric movies like Flicka and Dreamer.
Legend of the Guardians: The Owls of Ga'Hoole had the best hold among nationwide releases, easing 29 percent to $9.4 million. After a slow start, the Zach Snyder-directed 3D animated adventure has earned $41.8 million in three weeks.

The week's other new nationwide release, It's Kind of a Funny Story, finished in 12th place with $2.8 million at 742 theaters.
