Hey, let's watch a pretty good Popeye cartoon, shall we? This is "The Paneless Window Washer," which was released January 22, 1937. Jack Mercer is the voice of the squinty sailor, Mae Questel is the voice of Ms. Oyl and Bluto is Gus Wickie.
In case you don't know: These Fleischer-produced Popeye cartoons were sorta unique in that most of the voice work was done after the cartoon was animated. At Disney or Warner's, the tracks were recorded and then the animators made lips move in accord with what the actors had done. At Fleischer's, they might prescore a musical number but most of the dialogue was done "to picture" with the actors dubbing completed animation. That's why lips often are not in sync and sometimes don't move at all. Years later, when the Fleischer Brothers were ousted from their own studio, new management went to recording the voices in advance and that eliminated most of the wonderful little asides and sounds that Mercer would mutter under his breath. They really help make this cartoon work.
