Aw, come now. All those public domain fairytales and legends were struggling to gain an audience in the contemporary media landscape without a company willing to take the risk of developing a new presentation and monetizing distribution - with the mere caveat of trapping all those dusty ideas in permanent copyright. We're lucky that our new shared stories will never be I in danger of fading into unpopularity due to copyright not being able to guarantee a framework for for-profit distribution.

Sure, the actual movie part - but the 20th century fox fanfare at the beginning? (I have heard nostalgia expressed specifically for that)

He wrote the fanfare too (the one that comes before Star Wars, which was an adaptation of the original).
