Expendables 4 Movie News: The next installment in the "Expendables" franchise is going to be grittier. Sylvester Stallone recently promised that Expendables 4 will be rated X. It has also been confirmed that Manny Pacquiao will be playing the victim.

Expendables 4 is set to begin shooting in The Philippines. There was a recent Expendables casting development, when it was learned that Manny Pacquiao was added to the cast as a "Rebel General." There is no word on how big a part the boxing champ will have in the movie.

Fans were disappointed when it came out that The Expendables 3 was going to be rated PG-13 to get younger viewers into the sets. Producer and star Sylvester Stallone says the lack of an R-rating cost the movie many views.

When Crave Online, asked Stallone if he regretted cutting the violence to get the younger demographics, he answered "Absolutely unequivocally yes. I believe it was a horrible miscalculation on everyone's part in trying to reach a wider audience, but in doing such, diminish the violence that the audience expects. I'm quite certain it won't happen again."

The upcoming Expendables 4 movie would be set in the Philippines with Manny Pacquiao as a villain.

According to reports, Arnold Schwarzenegger and Sylvester Stallone recruited Manny Pacquiao right after his recent bout with Algieri in Macau.

The Movie Daily reported that Manny Pacquiao would play the role of a "vicious rebel general".

Youth Health Magazine reported that Sylvester Stallone and Arnold Schwarzenegger went to Manny Pacquiao's locker room during the fight against Chris Algieri. They said they were there to wish him good luck, but a spokesperson for Manny Pacquiao said Stallone and Schwarzenegger were there to recruit him for The Expendables 4.

The Rock is also on record as saying he wants to join The Expendables team. He recently told media "I don't want to be on their team and be buddies with them. Fuck that noise. I want to hunt every single one of them down."
