If there's one thing that The Expendables 5 may need, it's an injection of new, exciting action stars to revitalize the franchise. Stallone and friends may have been on to something with previous entries in the franchise, but the third movie didn't fare well and even returning to an R-rating for the fourth movie didn't help. The Expendables 4's abysmal performance at the box office is a clear indicator that the series could use new blood to take it off of life support.
