@Kyeh@tweezak (this question is in my wheelhouse re: useless information). I definitely consider Tom and Jerry (at least the good ones- racking up 7 Academy awards) a product of MGM studios. It has passed hands a few time since their heyday.
Hanna and Barbera were indeed the creators, but were just employees of MGM until 1957. Hanna/Barbera as a studio made more Tom and Jerry cartoons in the 70’s, but that incarnation (when Tom and Jerry were friends) was not so good. H&B had a third run with “Tom and Jerry Kids” in the 90’s - another not-so-good adaptation.
Speed Racer was where I first noticed that Japanese animation contained So Many Shortcuts, and employed endlessly repeated cliches; to me it seemed like it was as original as the 57 millionth Big Mac - and that was long before the Anime craze had become A Thing in the US. For that matter, it was before the expression “had become A Thing” had entered the vernacular in the US. Yeah, I’m that old.
