Helmut was a Nazi officer under orders from Walter Donovan in Hatay in 1939. During the journey to the Canyon of the Crescent Moon, Helmut chauffeured Donovan in the Hatay Renault 6CV Torpédo given to him by the sultan.
At the Temple of the Sun, Helmut kept his weapon pointed at the entrance way to the temple's three trials while a Hatay soldier attempted to bypass the first: Breath of God.
When the Hatay soldier was decapitated like Massad before him, Donovan commanded Helmut to bring forward another "volunteer". While Helmut and a colleague carried out the order, Indiana Jones and his group were captured, and Helmut was directed to stand down, for Jones would be taking the volunteer's place.
When Elsa Schneider crossed the threshold with the Grail, causing a cataclysm that threatened to destroy the temple, Helmut and the other Nazi soldiers ran, leaping over the crack in the floor that formed. They barely made it and thereafter ran out.
Behind the Scenes
- According to his shoulder insignia, Helmut is a captain. However because the Nazis in Hatay are wearing Heer (Army) uniforms, but taking orders from an SS officer, it's unclear whether Helmut would be a hauptmann (Heer) or haupsturmführer (SS).
