Now that we know the storyline for Crank 2: High Voltage is going to be a little wacky, it might give these latest behind-the-scenes photos some context. The Bad and the Ugly scored some pictures of the returning Amy Smart in all her topless glory (the pics are a little NSFW, so consider yourself warned), along with Jason Statham, and Corey Haim (rocking one heck of a mullet) hard at work on the action thriller.

Picking up where the last film left off, Statham returns as Chev Chelios, the hitman with a need for adrenaline. This time, though, he's got a busted artificial heart that requires jolts of electricity to keep it pumping. There is also something about a 100-year-old gangster named Hu Dong, but it all gets a little confusing after that.

Earlier in the week JFX Online paparazzi had taken some photos on set (mainly of Smart), but had been asked to remove them (the photos are still all over the web, so JFX has since put them back online). Their reporter even took a few cheap shots at the production, but has since retracted those comments. Writer-directors Brian Taylor and Mark Neveldine have already taken their fare share of criticism for the first film, but I know for a fact there are plenty of people who couldn't care less about the critics, and they can't wait until Crank 2 hits theaters in 2009.
