Since the first half of the series was primarily about building a foundation for what was to come, there were not a lot of creatures or other new vfx designs. "It was mostly transitioning Hawaii to whatever we needed it to be," explains Mitch Suskin, the new vfx supervisor on LOST, noting that several scenes took place in locations such as Los Angeles, Berlin or the desert. "It's about making the most of Oahu, and removing Oahu when we needed to. In the first half of the season, vfx was playing a supporting role."

The lack of showy creatures did not mean the vfx crew was not busy, however. "It was mostly the invisible type of vfx," says Suskin. Viewers probably were not aware that underwater scenes or shots of Faraday parachuting included vfx shots, for example, or that the satellite phone or GPS tracking devices that play a central role in the series are almost all vfx.

"Whenever you see that [GPS device], it's a block of wood, basically," Suskin adds. In the beginning, the producers didn't realize the device would be used so much, so they didn't build a prop, using vfx to fill in the backlit screen and other details.
