You can find lots of full films from throughout their history up on the NFB site (you can limit it to animation too, if you’re so inclined).
To offer an operatic counterpart, here’s the opening of Ottorino Respighi‘s 1922 opera, La Bella Dormente nel Bosco (available in full on Spotify too).[youtube http://www.youtube.com/watch?v=xJGEAhDqaRU&w=350&h=300]
It was actually performed in 2005 by New York’s Gotham Chamber Opera in conjunction with Lincoln Center Festival and puppets by Basil Twist, as seen below. Both the GCO & LCF have exciting events coming up this summer, so check them out. audio
