Melbourne: Although ‘Expendables’ has just released, director Sylvester Stallone is already planning a sequel for the action flick.
The movie stars the who`s-who of 1980s and 90s action stars - Stallone, Dolph Lundgren, Bruce Willis, Jet Li, Arnold Schwarzenegger and more.
"I believe this group (of characters) has to continue to evolve; it just can`t become the same people," The Herald Sun quoted Stallone as telling the Hollywood Reporter.
"So how do you get new people introduced into the group, and how do you have some of the other people leaving? Those are the challenges," he added.
Stallone said he never expected ‘The Expendables’ to top the weekend box office, but that the film topped his "proudest moment" in movies.
