LOS ANGELES - "Shark Tale" remained the big fish at the box office, with the animated comedy taking in $31.7 million to hold the No. 1 spot for a second straight weekend.

Billy Bob Thornton's "Friday Night Lights," based on the real-life fervor for high school football in small-town Odessa, Texas, debuted in second place with $20.6 million, according to studio estimates Sunday.

Another holdover, the firefighting drama "Ladder 49," came in third with $13.3 million, while the Queen Latifah and Jimmy Fallon action comedy "Taxi" had a so-so opening weekend of $12.05 million to place fourth.
