Despite the lukewarm reception for "The Expendables 3," Nu Image and Millennium Films are charging ahead with the fourth installment in the action franchise.

Variety reports the producers have already secured Chinese distribution for "The Expendables 4," which will shoot next year for release in 2017.

No director or cast has been announced, but Hulk Hogan revealed earlier this year that he's spoken to Sylvester Stallone about playing one of its villains. Stallone has also mentioned he'd like to recruit Dwayne Johnson and Bollywood star Salman Khan.

"The Expendables 3" grossed just $39.3 million in North America, but pulled in $78 million in China on its way to a worldwide total of $206.2 million (less than the first two films). Unlike "The Expendables 3," the upcoming movie will be rated R.
