The earliest cartoons I remember are from the sixties: Kimba was my favourite, but before that was Speed Racer and my earliest favourite, Gigantor.
Interestingly, I don't have clear early memories of the American ones, such as Hanna-Barbera and Warners. The former had a string of cartoons, the earliest of which I saw would have been Huckleberry Hound. Warners didn't really figure until the later Roadrunner, with a smattering of Bugs and Daffy before.
The production dates of these cartoons may not have been relevant: in New Zealand, I have a feeling they were rather like a bad day at a train station (running late, and out of timetable order). All seen in black and white only.
Those I particularly liked or remembered - mentioned up top - were all Japanese (although I didn't have a clue at the time). Maybe the American ones were too homogeneous: mostly anthropomorphic animals. Those Japanese cartoons were somewhat crude, but stylistically distinctive. But I'm not sure what appealed to my young mind. Plot? Characters? Unusual situations?
So Speed Racer has been revived for the big screen (following Kimba's conversion to the Lion King). Nothing like the original, of course, which makes me wonder what was there of intrinsic merit that compelled the plundering. Maybe no specific spark is needed, bar the producers' childhoods. Hanna-Barbera's been up too, via Jetsons and Flintstones.
Nothing so far has impelled me to see the big screen versions. Gigantor was my earliest favourite... let's see.
