A fresh bunch of recruits joins Sylvester Stallone, Jason Statham and their band of ageing action heroes for another round of old-school mayhem and self-mocking quips.

The newcomers include Antonio Banderas and Wesley Snipes, while the plot amid all the outlandish violence  involves Mel Gibson as Stallone’s presumed-dead friend, now a ruthless arms dealer.

Harrison Ford pops up to fly a helicopter, Banderas provides unfunny comic relief as an absurdly chatty assassin and Arnold Schwarzenegger appears uncomfortable – though Gibson looks like he’s really enjoying himself and puts some meaty menace into his sly, villainous role.
