Indiana Jones and the Last Crusade

The man with the hat is back. And this time, he's bringing his Dad.

An art collector appeals to Jones to embark on a search for the Holy Grail. He learns that another archaeologist has disappeared while searching for the precious goblet, and the missing man is his own father, Dr. Henry Jones. The artifact is much harder to find than they expected, and its powers are too much for those impure in heart.
