Wallace is a character from Prometheus. He is played by actor Eugene O'Hare.

Wallace is a crew member on board the Prometheus. He is one of the mechanics who gives maintenance to the all-terrain vehicles used to explore the surface of the LV-223 planetoid during the mission.

During Fifield's attack of the hangar bay he is the second crew member killed by him.

When the horribly mutated Fifield kills another mechanic, all that Wallace can do is watch in horror. Suddenly, Fifield pulls Wallace and throws him down. The monster then jumps on top of Wallace and crushes his chest, disabling and wounding him. Wallace is finally killed when Fifield smashes his skull against the floor with his bare hands.
