If you loved Gamer, try Crank: High Voltage
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Brian Taylor, Mark Neveldine, and they both carry the neon soaked, pitch black mood tags, and they sit in Action / Thriller territory. If that's the register that drew you to Gamer, the second film will land in a comparable space — through a different lens.

What Crank: High Voltage is
Los Angeles, a city in chaos, a defibrillator buzzing. A stolen heart, a battery-powered replacement, a man on the run to keep his ticker charged. Neveldine and Taylor push action to the breaking point.
