A good chunk o' the cast of The Expendables 3.

Sylvester Stallone and his awesome band of old crows take some major missteps in The Expendables 3—an unfortunate leap backward for the aging-action-star franchise.

Stallone and company jettisoned the smarmy Bruce Willis in favor of the growly Harrison Ford, and this is a great change. They also added Wesley Snipes as Doctor Death, Antonio Banderas as fast-talking comic relief and, most notably, Mel Gibson playing himself (aka The World’s Biggest Asshole).

Stallone and director Patrick Hughes should’ve stopped right there and given the group (which also includes Arnold Schwarzenegger, Jason Statham, Dolph Lundgren and many others) a decent script. This is a sufficient cast for any action movie—so get cracking with the pyrotechnics, and focus on a story that makes sense!

Alas, that didn’t happen. Perhaps because the production could only afford the big guys for a minimal amount of time, the script has Stallone’s Barney Ross putting the old guys on ice after the first 30 minutes in favor of a new, mostly younger crew—and most of that new crew is uninteresting and lacks the charisma of their older counterparts. Too much screen time is given to the likes of mixed martial arts superstar Ronda Rousey, who can most certainly kick the shit out of people, but can’t act for squat. Names like Kellan Lutz (the Twilight films) and boxer Victor Ortiz round out the boring faction of the new cast.

The plot is a mish-mosh of action-movie clichés, as Barney finds himself gathering the new team to go up against Stonebanks (Gibson), a former Expendable turned arms dealer and bad guy. Gibson gets a couple of scenes to show off his catcher’s-glove face (seriously … stop smoking, Mel!) and act all crazy.

After some tedious scenes introducing the new crew (featuring Kelsey Grammer, of all people), Barney eventually lets the old guys back into the movie, and this results in a halfway-decent finale during which many things blow up. It also has a typical showdown between Barney’s good guy and Stonebanks, during which the villain gets the upper hand, yet throws away his weapon in favor of hand-to-hand combat. Gibson vs. Stallone is a bit outlandish, even if Stallone is something like 95 years old.

I did like the sight of Harrison Ford piloting a helicopter, Han Solo-style, and Snipes is fun in his few scenes. The screenplay has a lot of inside jokes about his tax-evasion jail sentence that warrant a chuckle or two. Dolph Lundgren’s “Sore Loser” T-shirt also put a smile on my face, as did Terry Crews, once again letting loose with his really big gun.

I don’t understand the Jason Statham phenomenon. He’s been OK in a couple of films, but most of the stuff he slums in is trash. I’m sort of grateful that this movie puts him into more of a background role.

In an effort to give the film more earnings potential, it was made for a PG-13 rating (while the previous installments were R-rated). Dumb move. The target audience for this sort of stuff likes movies filled with bloody carnage and F-bombs. This boneheaded move, along with a pirated copy of the film that has been downloaded by millions, resulted in The Expendables 3 having a bad box-office opening.

Unless this movie catches fire overseas, the franchise may be in jeopardy. If you can’t get it done in the third installment, you are usually toast in Hollywood.

The Expendables 3 is now playing at theaters across the valley.
