LOS ANGELES (AP) - Sylvester Stallone and his beefy buddies have muscled their way to the top of the weekend box office.

Stallone's action hero roundup "The Expendables 2" debuted at No. 1 with $28.8 million. That's down from the $34.8 million start for "The Expendables" two years ago.

The Lionsgate sequel elbowed out another action tale as Universal's "The Bourne Legacy" fell to No. 2 in its second weekend with $17 million.

Three other new wide releases opened to modest business: Focus Features' animated adventure "ParaNorman" was No. 3 with $14 million; Sony's music remake "Sparkle," featuring Jordin Sparks and Whitney Houston, was No. 5 with $12 million; and Disney's family fantasy "The Odd Life of Timothy Green" was No. 7 with $10.9 million.
