One thing to note about the old Fleischer footage is that it has a new soundtrack recorded by Jack Mercer, Mae Questel, Jackson Beck and music director Winston Sharples.
I would have been nice if the late Willard Bowsky got animation credit for the old footage. In case you didn't know, Bowsky was the head animator for the original "Popeye the Sailor Meets Sindbad the Sailor" footage. Bowsky joined the U.S. Army after Pearl Harbor and was killed in action in France.
Besides the number of nephews reduced to three (which one fell victim to budget cuts?), it's noteworthy that this cartoon features Popeye in his original sailor outfit before he joined the U.S. Navy at the end of the Fleischer era.
