'Seabiscuit' takes in $21M

"Seabiscuit," the $90 million movie based on a best-selling book about the 1930's-era Hall of Fame horse, took in an estimated $21.5 million in box-office receipts during its opening weekend.

"Seabiscuit" was the fifth-highest-grossing film of the week, well behind "Sky Kids 3D," which had $32.5 million in ticket sales, but close behind "Pirates of the Caribbean," "Bad Boys 2," and "Lara Croft Tomb Raider 2," which were all within $1 million in ticket sales.

"Seabiscuit," however, appeared on at least 1,200 fewer screens than the higher-grossing movies, according to Exhibitor Relations, which tracks ticket sales. According to the company, "Seabiscuit" had the highest per-screen average of any movie last week, at $10,809. The movie appeared on approximately 2,000 screens.
