Oskar Schomburg stayed aboard his submarine and was not involved in the apprehension of the Ark or Marion Ravenwood, leaving that task to Colonel Dietrich and René Belloq. When the U-boat arrived at Geheimhaven, Schomburg stood in the vessel's conning tower as Belloq, Dietrich, and Toht disembarked.
Behind the scenesEdit
The uncredited role of the submarine captain, named in Lawrence Kasdan's script as "The Wurrfler Captain", was played by the late Michael Sheard, who had originally auditioned, unsuccessfully, for the role of Major Toht. Sheard later went on to portray Adolf Hitler in Indiana Jones and the Last Crusade.
The captain has additional scenes in the film's script but, according to Sheard, the scenes were never shot and his character only appears on-screen standing in the conning tower of the submarine. This happened due a change in weather which resulted in the film's crew moving on to Tunisia while Sheard traveled to Scotland to fulfil a commitment that he had with another production.
The Raiders of the Lost Ark Sourcebook later identified the Wurrfler captain as Oskar Schomburg, though the historical Schomburg commanded U-26 in 1938 and 1939. U-26 was captained by Werner Hartmann in 1936.
