They mention it, but, it just isn't true. Splash mountain could have been made if SotS never existed because that part of the movie was directly from Uncle Remus Stories. I'm not sure how that can be denied. None of the characters of the live action part are anywhere to be found. It is easier and, so much more newsworthy, to claim that it is based on SotS. Way to much explaining has to be done to see it from the reality point. So, if you want to believe that it is based on SotS, I will never convince you otherwise, but, other then the songs used its base has nothing at all to do with the movie. SotS isn't even in the name of the attraction. It's so easy not to recognize the literary connection, and go with the talking points. Simply put, years ago Disney created a movie based on the U.R. Stories (the cartoon parts are the UR connection) Many years later Disney created a park attraction based on the U.R. Stories (the show scenes and the story lines are the UR connection). And there is no other connection other then music, which theoretically could have been composed without ever having the movie..
