In comparison to the first movie, The Expendables 2 has even more recognisable actors with the addition of Chuck Norris, Scott Adkins, Jean Claude Van Damme and Liam Hemsworth. Bruce Willis and Arnold Schwarzenegger also get a lot more screentime but unfortunately Jet Li disappears from the movie after just a few scenes.
In terms of the violence, The Expendables 2 is equally as violent as the original. Over the course of the movie you will see men killed with truck mounted machine guns, one character blows people apart with a 50 calibre sniper rifle, two men get riddled with bullets and you see the bullets impact their body and one of the main antagonists gets his head shoved into a helicopter rotor towards the end of the movie.
The cast in this movie consists of Sylvester Stallone, Jason Statham, Jet Li, Dolph Lundgren, Chuck Norris, Terry Crews, Randy Couture, Liam Hemsworth, Scott Adkins, Nan Yu, Jean Claude Van Damme, Bruce Willis and Arnold Schwarzenegger.
Overall, The Expendables 2 is a very good and enjoyable movie for anyone who liked The Expendables, who likes old style action movies or who grew up with movies such as Rambo, Die Hard and Terminator.
