Quoted from joetechbob:

Somewhat off topic, but I've been watching some of the older Superman cartoons with my kids and really dig them: » YouTube video
Really like the art style, animations and sounds. And the episodes I've watched have been entertaining/hold up well (IMHO).

Quoted from joetechbob:

Interesting backstory on that which I hadn't looked into before:
"Paramount was interested in financially exploiting the phenomenal popularity of the then-new Superman comic books, by producing a series of theatrical cartoons based upon the character. The Fleischers, looking for a way to reject the project without appearing uncooperative, agreed to do the series—but only at a (intentionally inflated) per-episode-budget number so exorbitantly high that Paramount would have to reject them, instead. They told Paramount that producing such a conceptually and technically complex series of cartoons would cost about $100,000 per short (in 1940s dollars, or $1,700,000 per short as of 2017); this was about four times the typical budget of a six-minute episode of the Fleischers' popular Popeye the Sailor cartoons of that period.[3] To the Fleischers' shock, instead of withdrawing its request, Paramount entered into negotiations with them, and got the per-episode budget lowered to $50,000.[4] Now the Fleischers were committed to a project they never wanted to do—with more financial and marketing support than they had ever received for the projects they had done."
