Indiana Jones and the Last Crusade1989

Professor Henry Jones:
Well, he who finds the Grail must face the final challenge.

Indiana Jones:
What final challenge?

Professor Henry Jones:
Three devices of such lethal cunning.

Indiana Jones:
Booby traps?

Professor Henry Jones:
Oh yes. But I found the clues that will safely take us through, in the Chronicles of St. Anselm.

Indiana Jones:
But what are they? Can't you remember?

Professor Henry Jones:
I wrote them down in my Diary so that I wouldn't have to remember.
