In the beginning driving a truck was just another job. Then one spring day in 1963 while

driving a Ford bobtail, a shiny red and white truck and transfer rig with 'Franklins Blocks'

painted down the side appeared from nowhere. Here, cruising slowly towing a fancy transfer

rig down Roscoe Boulevard, was an unheard of model 352 Peterbilt with butterfly hood;

280 cummins; and polished aluminum wheels.
"With one look at that arrogant top-of-the-heap cigar smoking driver, I was hooked," said George.

" I wanted to be THAT guy."
So hooked was George that he indefatigably hauled asphalt by day and pumped gas by night in

persuit of his newfound obsession.
Later George recalls, " The cigars caught my pants on fire and gave me a headache. That was

Ok because within a year I was cruising down Roscoe Boulevard in a shiny 352 Pete with

butterflyhood; 280 cummins; and polished aluminum wheels. Man, I was coo!"
George's need for excitement and thrills led him to truck racing at RockingHam Raceway in North Carolina. The trucks George raced ran at speeds up to 130 miles per hour. Closer to home George can still be found racing dwarf and sprint cars around dirt tracks in southern California.
George Sack's introduction to the movie industry came at age 17. He ditched school to work as a stand-in and extra in the now classic film, "It's a Mad Mad Mad Mad World." His first big gig was as driver/ stunt driver for the 1970s hit TV series, "BJ and The Bear." From there, George's long list of credits reads like and ecclectic commercial marketing resume. Brand names like: McDonalds, Chrysler, Chevy, Carl's Jr., Pizza Hut, Volvo, Lexus, Frito Lay, Coors Light, and Pacific Bell, have all featured George's stunt truck driving with his famous jackknife rigs.
Motivated by the need for a safer reusable jackknife setup, George invented and developed the first driver controlled  jackknife tractor trailer rig. The rig can be customized to work on virtually any semi trailer. Even more impressive is the fact that George can jackknife a trailer to either side, or alternating sides. This unique rig makes resets and multiple-camera-angle-shots practical and efficient. Word of George, a.k.a. the Jackknife King, and his innovations in truck stunts and rigging designs quickly spread throughout the industry. Virtually every jackknife rig used today is copied from the Jackknife King's original design.
Hollywood has repeatedly called upon George to perform the most difficult jackknife 'gags' exciting movie audiences worldwide. Below are a few of his better known contributions to film.
The Horse Whisperer  Opening riding sequence: As a loaded semi approaches, the two horseback riders decide to go for it, launching accross the road and up the slippery hillside. The first horse rears up sliding backward down the hill into the second horse and rider. The group ends up back on the road  in a heap, directly in the path of the oncoming truck. The trucker, George, eyes bugging out  slams on the brakes and jackknifes the trailer. Pilgrim, the hero horse, bravely stands up shielding the little girl and inviting certain death in the form of the oncoming truck.
Frequency     Opening crash sequnce on the Fort Lee bridge: The tired trucker, played by George Sack, looks down briefly to change the radio station while exiting the Fort Lee bridge. Up ahead a careless road crew forklift operator accidentally dumps onto the roadway a huge load of steel pipes . By the time the trucker reacts, it's too late. The truck swerves to avoid the pipes but skids violently out of control jackknifing the trailer. The heavy skidding trailer breaks loose from the truck hitch rolling over on its side before finally coming to rest.
Three Kings In a poor Iraqi village, post Desert Storm: An approaching cloud of dust reveals a crazy Iraqi throttling an old rusty tanker truck toward the village gates at high speed. Fearful of attack the village gaurds open fire with automatic rifles and rocket propelled grenades. The driver reacts instantly swerving left. The extreme force of the sudden turn lifts up all of the driver side wheels as the rig arcs 360 degrees before being hammered by an RPG round. The exploding grenade rips a gaping hole in the tank sending 10,000 gallons of precious milk gushing uselessly to the village sand.
Terminator 3  Griffith Park chase scene: The hero, ARNOLD, driving a commandeered hearse, attempts to shake off the attacking terminator clinging to the vehicle roof. Arnold while speeding towards a slow moving truck suddenly swerves underneath  the orange and blue Xenadrine semi trailer shearing the roof from the hearse and sending the blonde female terminator flying. As the topless hearse speeds safely away, the concerned trucker, George, runs back to check for survivors only to witness the terminator testing out her flame thrower- arm on the dry brush. The next shot is a close up of George. He screams, " Oh s**t, I'm out 'o here!" , then he spins and sprints off.
Experience breeds knowledge and skill in one's craft. George Sack Jr. has over thirty years of stunt driving experience. To get the best shot you want the best talent. George gets the job done.
