The team had two effects with vehicles that did not perform as originally planned. The first, in "Rush", involved a scene where Pete and Chloe intentionally drive their car off a cliff and Clark speeds in to catch it before it hits the ground. To attain the shot of Clark catching Pete's car required the crew to suspend the car from a crane with Sam Jones III and Allison Mack inside the car. The scene was filmed in a rock quarry, as there are not many cliffs in the Vancouver area, with segments of the scene created digitally. The car was then filmed as it was being pulled into the air backwards—the footage was then reverse to give the impression that it was falling. Initially, Mike Walls and his crew tried to pull the car straight up, but it was not working. The movement of the car had to be tweaked to give a sense of reality. In the season finale, Jonathan and Martha crash their truck on their way home after an EMP blast, which Clark caused, sends a shock wave out that downs a telephone pole and their truck hits it. In order to get the Kent truck to roll for the moment where Jonathan and Martha encounter the wave of EMP, two stunt drivers drove the truck toward a collapsed telephone pole, skidding into it. Then, with mannequins in the truck for safety, the effects team wrapped some cables around the truck and launched it off a ratchet to make it roll. Unfortunately, this did not go as smoothly as planned the first time, as the telephone pole did not fall when they set off the explosive charge to break it. Since it would be too hard to strap John Schneider and Annette O'Toole into the truck while it is upside down, and too dangerous to flip the truck with them already in it, Mike Walls and his team built a rotating truck seat, which allowed them to strap Schneider and O’Toole in, then rotate the seat so that they are upside down and slide that into the overturned truck.
