The zeppelin in Last Crusade was not the Hindenburg. It was D-138, a zeppelin operated by the same company as the Hindenburg and designed after it. But the Hindenburg disaster occurred in 1937 and Last Crusade was set in 1938. Also, Sallah was played by John Rhys-Davies in Dial of Destiny in addition to the 2 movies that you listed.
How many did you get right?
