At long last, a rumor about the fourth "Expendables" installment people can sink their teeth into. Rumor has it that Sylvester Stallone is finally writing the script and has started casting (famous) actors.

According to Youth Health Magazine, Hulk Hogan and Dwanye Johnson are two possible villains for "Expendables 4." Stallone is looking for new faces that will bring life into the aging-hero franchise. In fact, he was rumored to cast Justin Bieber and most fans find it as frightening as one of the villains.

During the Body Power Expo at NEC Arena in Birmingham, England, Hulk Hogan said, "We're trying to figure out a way to maybe turn me into the most evil man in the world."

"You know, Stallone gave me my first break. He's been a great friend for all these years. We had a great conversation, talking about the possibilities. Can I still run, can I still jump? Well, not as fast or not as high, but I think Hollywood could find a good stunt man to help me out."

Other than the reported addition of the veteran wrestler based on a report from IGN, Jason Statham expressed his desire to work on more "Expendables" movies.

During an interview with Arnold Schwarzenegger, USA Today said that the Terminator icon believes that there's still room for one more movie in the franchise.

"I just think it's a terrific franchise. I told Sly to write another one or have someone else write another one. A really terrific story because I think it's a great idea to have an ensemble piece with that many action heroes in a movie. Especially if the comedy is really done well, it could be a great story. There's definitely room for another one."

Ronda Rousey, Wesley Snipes, Mel Gibson and Antonio Banderas - all of which are in the roster - firmly believe that the third movie was a catastrophe. This was due to a leaked copy of the movie that spread all over the Internet three weeks before its release. Because of this, "The Expendables 3" struggled in the box office with only $206 million worldwide and $15.9 million during the opening.

"The Expendables 4" is currently in the works and the rumor mill is hard at work. One speculation involved the name of Manny Pacquiao, but there is still no confirmation from the Philippine Pride.
