Continuity mistake: In the opening cutscene for Temple of the Grail, Indy, Henry Sr and Sallah are standing outside the Grail Temple. Indy is walking off-screen whilst Henry Sr and Sallah talk briefly, but when the level starts, Marcus Brody has suddenly appeared with the group out of absolutely nowhere. He was never shown with the other three at any point before this in the cutscene nor was he ever shown with them at any point in the previous level.
