I was watching Pink Floyd Live at Pompeii and I noticed a lot of errors occuring through out the film.
First of all why in the hell is the credits in FRENCH. I know it was made by the French but they didn't dub or even sub-title the rest of the film (which isn't a bad thing).
ECHOES
If you listen very closely at the begining of Echoes, Rick Wright is playing the Piano BUT you can hear his Organ in the background. I always though it might be Roger Waters, but you can see him play his Bass.
Notice one minute were Nick Mason is wearing sunglasses and the next minute they're gone and back on again.
CAREFUL WITH THAT AXE....
SET THE CONTROLS......
My own personal opinion they did these in the studio. Looks like Rick shaved his beard off sometime during the trip eh!!!!! Those big lights in the background makes it look like a studio atmosphere. How can they get power when there is no sun!!!! A lot of the close up shots were all four are in one shot, must of been a second take. Sometimes whatever they are playing doesn't match what we hear (especially with the drums)
A SAUCERFUL OF SECRETS
Shot at two different times of the day. Either at sunset (which is my best guess) and in the middle of the day. How do I know this....look at the sun direction on each shot. Notice where Ricks piano is when he is banging on the keys and then look where it is when he starts to play the Hammond Organ.
The fake wind effects are not present in the complete band shots with all four.
