I have been up to Avdat today and I think I recognize it being used in a few scenes of the 1973 movie version of Jesus Christ Superstar, but of course it's really hard -- obviously they "dressed" the ruins. Is there any information about the specific locations where they filmed the movie?
A Songfacts interview with Ted Neeley offers the following shooting locations;
"Trial Before Caiaphas" was shot on the site of the Herodian fortresses near Bethlehem.
"The Temple" and "The Crucifixion" scenes were shot at Avdat.
Ein 'Bokek provided the location for "Pilate's Dream."
"What's the Buzz" truly was under the Dead Sea... in a cave [The Beit Guvrin Bell Cave]. The same cave served as Neeley's "prison" after "The Arrest."
For "King Herod's Song," the crew set up shop on the Dead Sea not far from Masada, where Herod actually once had a summer palace.
An ancient Roman ampitheater in Beit 'Shaan, tunneled through with catacombs, served as the location for "Trial Before Pilate" and "Superstar."
Note that I've corrected a couple of the place name spellings for ease of reference.
