and quote from this page:
Regarding the identity of the character of Otto in the film, Lucasfilm Story Group's Pablo Hidalgo writes:
"We found a call sheet with Christopher Frederick for one day only -- a day of shooting inside Marion's tent. Because all the other characters in the call sheet are identified, we figure he is either the Arab servant that sets up Belloq's dinner, or the German soldier that pushes Marion into the tent, but there's currently no way to identify him beyond that."
The website Aveleyman.com however reveals Christopher Frederick's appearance, in an episode of BBC Plays, Caught on a Train, as a German guard. Although the character of Otto is not clearly seen in the tent scene, Frederick's facial shape most closely resembles the German soldier rather than the Arab servant.

Submit all evidence as instructed.
Provide the last known contribution number.
And no. IMDb WILL NOT be checking with someone else to verify a credit of yours.
And lastly follow these directions given, or don't.
You have been given good advice yet you ignore it.
Do as asked please.
As staff said, don’t try just to ”delete” the credit from your name page. You need to go the title page of ”Raiders of the Lost Ark”, click ”Edit”, choose ”Cast” and ”Correct”, and then change the name ”Frederick, Christopher (I)” to ”Frederick, Christopher (II)” (the latter being your name). Don’t choose the option ”delete”, choose ”correct”.
But since I have to assume that you already tried that, it’s probably best to contact IMDb Help Desk, or wait if the IMDb staff answers again. I would advice not to post any sensitive/private info in this thread (public forum, and all).
