Expendables

Short Answer: Even more action actors

There is a pattern we see in any number of movies: Collect Them All. Often, it is a bunch of similarly themed animated animals off on an adventure-- woodland ones, Ice Age ones, zoo animals, tropical birds, etc.

For action movies, this often translates into putting all the superheroes in one team. In the case of the Expendables movies, the idea is to collect all the acton stars from the 1970s and '80s-- when action stars were not super or magical-- and put them in a movie. 

They were, basically, cowboy heroes, but in city (or maybe wilderness) environments-- take Charles Bronson, who went from Westerns to the Death Wish movies. They could punch, maybe kick. They could run, jump, and shoot. Some could work grenade launchers or fly helicopters. That was about it, but it was enough to kick the bad guys' butts. 

Well, even three movies in, the Expendables forgot Kurt Russell and Rutger Hauer.

Also, if Jet Li and Chuck Norris are in the series (which they are, or I would not be bringing it up), then where is Jackie Chan? And several other martial-arts superstars I could mention? Chow Yun-fat comes to mind. David Carradine. 

Also, I see Wesley Snipes, but where is Richard Roundtree? Michael Jai White? Billy Dee Williams? Mario Van Peebles? Danny Glover? Rocky actors Carl Weathers and Mr. T? Action comes in more than one, um, color.

There are also two few women in the mix. Linda Hamilton should be there. Sigourney Weaver. Pam Greer. Michelle Yeoh. The late 1970s ushered in an era of damsels who were not all that distressed and could rescue themselves, thank you very much. By the 1980s, women and whoop-ass were a common team. 

The Expendables should be... expandable.
