Dr. Lawrence Gordon, played by Cary Elwes, is a character in the film Saw.
Lawrence Gordon is the man who diagnosed John Kramer's terminal cancer and was initially a suspect in the Jigsaw murder case. John targeted Lawrence for being cold and uncaring to others, and for cheating on his wife Alison by having an affair with his medical student, Carla Song. Lawrence was placed in a trap alongside Adam Stanheight and was tasked with killing him before six o'clock or his wife and daughter would be killed. He failed to do so, but severed his own foot to free himself from his shackle, and crawled away to get help, promising Adam he would bring someone back. His fate is unknown until Saw 3D, when it is revealed that Lawrence passed out after using a hot steam pipe to cauterize his ankle stump. John found him unconscious shortly after and congratulated him for surviving. He then helped Lawrence recover, and gave him a prosthetic foot.
John recruited Lawrence afterwards, and used his medical skills to prepare other traps. He prepared a variety of traps for John, such as putting the key in Michael's eye in the venus flytrap (Saw II), as well as sewing Art Blank's mouth and Trevor's eyes shut for the mausoleum trap (Saw IV). He also selected Lynn Denlon as John's surgeon (Saw III) and wrote an anonymous message to Detective Mark Hoffman (Saw V) stating "I KNOW WHO YOU ARE". Following John's death, his ex-wife Jill Tuck delivered a package to Lawrence that had been left to her in John's will; it contained a videotape with instructions from John to watch over Jill and act on his behalf if anything was to happen to her. When Hoffman kills Jill and attempts to flee the city, he is ambushed by three people in pig masks, led by Lawrence. After chaining Hoffman by the ankle to the pipes in the bathroom (which also reveals he did not return to Adam as promised), Lawrence picks up the hacksaw he had used to sever his own foot and throws it into the corridor. He then turns off the lights and leaves, and despite Hoffman's protests, closes the door and leaving Hoffman to die in the darkness of the bathroom, with no means of escape.
