No, he did not. Special effects were used as detailed below.
JAG' effects
Throughout the fall, viewers have called and e-mailed, wondering how the producers of "JAG" make actor Patrick Labyorteaux appear to have suffered the same leg amputation as his character, Lt. Bud Roberts.
"He wanted to keep his job and he's a master of his craft, so he went out and blew up his leg," said Avery Drewe, a "JAG" post-production producer. He's kidding, of course. Drewe said the missing leg is achieved through a combination of effects, including Labyorteaux wearing a prosthesis and bending his leg so it's bound up behind him in a specially created rig.
"We work carefully with the camera angles so when he's walking toward us we can't see that," Drewe said. If his leg should peek out, it's digitally erased in post-production. A scene where Bud walked up the stairs combined special effects shots of Labyorteaux with shots of a real amputee. Now Bud has recovered to the point that he walks using a prosthetic leg with only a slight limp.
"Our writing staff wanted to make it accurate, so we tracked what the real progression would be," Drewe said.
