I always assumed that this final scene in “Indiana Jones and the Last Crusade” (1989) was filmed on location in Petra, Jordan. That building carved out of a rock wall is real. But on second look, I think the actors are blue screened in to the location.
(This was 1989, before they were using GREEN screens, BLUE was dominant).
What do you think?
Maybe the area in front of the real Petra is too narrow to fit a film crew?
