I think a lot of the "racial" stuff is the censors being a bit too sensitive there is a lot of racism in this world but i think banning and cutting certain cartoons makes it worse. It makes the issue far more sensitive and then people become less aware. However i know they had to change the original release of Spiderman the Movie because one of the scenes had spiderman spinning a web between the two towers
That scene was never in the movie. It was specifically shot as a trailer. They just pulled the trailer from theaters.
Looney Tunes were NOT affected by 9/11 at all. Those cartoons have been out of circulation for 10+ years mostly for not being very PC and offensive to blacks, asians, etc.
Look at Disney's "Song of the South", same reason that's dissapeared, and why Fantasia was edited to cut out the little "sambo" kids who clean the Centaurs hooves.
The Tex Avery cartoons still air, on TCM. I think two Saturdays a month.
I used to work for the Cartoon Network in the UK in 2003 and the only time we pulled some Looney Tunes cartoons was during the US invasion of Iraq some of the more over the top and violent WWII era ones were pulled off for a bit. But that's about it, and that had nothing to do with 9/11.
