Was Walt Disney a free mason?

I was watching this youtube video about the "evils" of Disney's corporation and it said that Walt Disney was a free mason (or some kind of Satanist.) I do admit that I've studied a few of his films and they have some pretty ****** up subliminal messaging hidden in them. For example the words "sex" and "lie" hidden in frames of The Lion King and the naked lady picture in that one shot of The Rescuers. Was Walt Disney really a free mason or was that person misguided? I find it kind of interesting.
