Like most action movies, “Crank: High Voltage,” the sequel to 2006’s “Crank,” has gunplay, car chases, gallons of blood — and Jason Statham. But those are just a few of the many ingredients thrown into the boiling stew of chaos, amorality and violence that is the movie, which goes beyond the limits of an action flick.

“Crank: High Voltage” begins with the exact scene that “Crank” left off with, in which professional assassin Chev Chelios (Statham) falls from a helicopter into the streets of Los Angeles. Through nothing less than a miracle, and because of his superhuman heart, Chev survives — the first display of the film’s bold embrace of the ridiculously improbable that most action movies try to avoid. After he is abducted by members of the Chinese mafia, Chev wakes up on an operating table and finds that an artificial heart pump has replaced his indestructible heart. He then begins a quest for revenge — and a search for his heart — while periodically exposing himself to electrical shocks to keep his artificial heart beating.

Statham departs from the cold, quiet persona he adopted in the “Transporter” movies, often becoming visibly angry as he desperately tries to find his heart and zaps himself with Tasers, jumper cables, electric dog collars and fuse boxes. His performance in “Crank: High Voltage” isn’t particularly memorable, but his portrayal of a wide range of emotions comes as a refreshing change.

The film’s selling point is its wild, erratic and random style that takes the audience on a roller-coaster ride through the streets of Los Angeles. The intense fights and gun battles are over-the-top — one two-minute scene features Chev doing nothing but throwing bodies through the walls and out the windows of a run-down hostel.

His encounters with strange supporting characters ensure the audience never knows what to expect. Venus (Efren Ramirez), a revenge-seeker who suffers from full-body Tourette’s, personifies the film’s out-of-control spontaneity with his outbursts. Careful production efforts, such as tight camera shots that get right in characters’ faces, make moviegoers feel involved in the chaos that they witness on-screen.

True to its no-holds-barred style, “Crank: High Voltage” blatantly disobeys the laws of physics and any political correctness to enhance its insanity. Bullets ricochet five or six times before hitting a random person straight in the head. Chev reacts to lethal electrical shocks as though they are mere doses of adrenaline.

Audiences should be prepared for the film’s intentional offensiveness. Not only is it fraught with foul language and gory violence, it’s extremely lewd. With the exception of a single female police officer, every woman plays either a scantly clad (if not topless) prostitute or stripper, and nearly every man plays a weapon-toting gang member or a sleazy supporting character. The shamelessness culminates in public fornication on a horse track. While moments like these are somewhat disgusting, they enhance the film’s exhibitionist quality.

Like most action movies, “Crank: High Voltage” is meant to entertain and nothing more. Overall, it succeeds in its amped-up portrayal of chaos and violence. It is exciting, funny, sickening, perplexing and anything but dull.

“Crank: High Voltage” was written and directed by Mark Neveldine and Brian Taylor.
