Hey, Tomasz. How did you found the info on Palestinian dubbing in general like "Holidays" for example. Did you find any info about the Palestinian voice actors aside from Taha Al-Abid. Whys Taha moved from Palestine to Lebanon? Can you contact Elrom Studios aka ELROM-PERFECTVOICES about how many shows, cartoons and movies dubbed into Arabic? Here's the link. http://lebanesedubbing.wikia.com/wiki/Thread:2435
Honestly, some of the shows that aired (or currently airing) on Cartoon Network don't even warrant the TV-PG rating, I'm talking shows like Teen Titans Go!, DC Super Hero Girls, Clarence, Uncle Grandpa for example. TV-Y7 at least.
