Those Goldurn Nazis!

In the scene where Indy and Sallah meet the old man, Sallah calls the boss german "Dietrich." I assume this is the Nazi who we see throughout the film and who gets all melty at the end. Later, Belloq calls him "Scliemann," which I assume is his last name. However, in the featurette "The Light and Magic of Indiana Jones," he's called "Wolf."

Next, is the Nazi Gobler, who follows Dietrich around, the guy who drives the black car all the bad guys are in or the guy in the jeep who falls to his death?

Finally, what's Toht's profession? Is he Gestapo or something?

 

I also get confuse on which Nazi is which. I don't think they even mention Toht's name in the film which adds to the confusion.

 

Wolf would seem to be the actors name.
