"Expendables 4" is once again ready to create explosions and send terrorists back running home as another installment of the movie Expendables is scheduled to be shot once more in the depths of the dark alleys and buildings of Bulgaria. The movie is set to be released by 2016 but a lot of names are already being rumored to be included in the movie. Is there a chance of seeing Justin Bieber, the legendary Hulk Hogan and the boxing champion Manny Pacquiao in one extravagant movie?

Terry Crews confirms that Justin Bieber will be casted in the 2016 action movie. A fan site of the singer, JustinBieberZone.com shared what Terry Crews has to say on Justin's participation in the movie. "The next one, I am telling you, Justin Bieber is coming for the Expendables 4. That is for real, Bieber in Expendables 4. We are going to shoot him all at the same time. It will be wonderful."

This might actually explain why we're seeing a lot of Justin Bieber is his "shirt-off" glory. He sure seems gain a few pounds over the years and had a few definitions added in his muscles. He's actually working out a lot lately. Is this the possible confirmation that he is indeed preparing for a role in the movie?

Mel Gibson wouldn't be part of the next installment of the movie series, because his character is already annihilated in Expendables 3. So fans of the franchise can expect a new formidable villain the Expendables 4. According to reports, the legendary WWE superstar Hulk Hogan will be the next villain in the movie. In an online chat last 2013, he was asked why he was not casted during the 3^rd installment of the movie. His answer, "Brother, they already had the actors. Relax. I'm in the fourth part."  Hulk Hogan and Slyvester Stallone are good friends and have worked together in 1082 movie, Rocky 3. It would definitely be exciting to see how the 61-year old Hulk will manage to fulfill his action scenes in the movie. He still looks awesome but followers have not seen him fighting on the ring for quite some time.

Meanwhile, rumors of Manny Pacquiao's casting in the movie are not stopping. In fact, Stallone and Schwarzenegger approached Manny Pacquiao  during his latest fight with Chris Algieri. Everyone seem to have thought that it was a simple meet and greet but sources are speculating that the two action stars are asking Manny to join the casts for the 4^th installment of the Expendables. How could Manny possible say no to the offer? It is assumed that Manny accepted the offer and the two action legends even left the room with contented smiles on their faces. Is this the reason why the Pacquiao-Mayweather fight has been delayed for quite some time? Is Manny going to skip his training to be able to participate in the production of the movie?

Manny Pacquiao's fight is still due this May and he has plenty of time to catch up on the production of the movie even before it airs this coming summer of 2016.
