I watched EARTH VS THE FLYING SAUCERS ON on TCM the other day
I saw this film as a kid in 1957 on a double feature with the original Godzilla. I was listening the other day with my headset and headphone amplfifier. TCM showed a version that had the mono sound redone in stereo. Boy did that rechanneling make this B-pict sound great. Good job whoever did this audio transformation. I believe this film is on BD with the 5.1 soundtract. If it sounds any good like what I heard it is probably nifty audiowise in 5.1.
