What do you get when you cross mixed martial arts (MMA) with 80's action stars?

The number one movie at the box office for the weekend of Aug. 17-19, 2012. "The Expendables 2," featuring former Ultimate Fighting Championship (UFC) Heavyweight and Light Heavyweight Champion Randy Couture, debuted in the number one spot with a gross of $28.7 million, according to estimates published on ComingSoon.net.

Good, but not great.

The sequel failed to match the $35 million the original posted in Aug. 2010, despite the addition of karate legend Chuck Norris, as well as more prominent roles for ex-box office juggernauts Arnold Schwarzenegger and Bruce Willis, who appeared in small cameos the first time out.

See how The Expendables 2 stacked up against the rest of the competition, after the jump.

1. The Expendables 2 ($28.7 Million)

2. The Bourne Legacy ($17 million)

3. ParaNorman ($14 million)
