Is there really masonic symbolism in the Disney movies?

I read the Da Vinci code, and in on part they talk about how Walt Disney was a mason, and incorporated masonic symbols as well as hiddden messages that dealt with pagan myth, and icons of the sacred feminine. Is this true? Also the book says that if you play a section of "The lion king" and do a freeze-frame in one part you can clearly see the floating dust particles over Simba's head that spell out the word . If anynone has seen any of these things can they give the example and where it is found in the movie.
