Disneyland employees in California, including those who perform as characters from Mickey Mouse to Moana, have voted to unionize. The 1,700 workers will be represented by Actors' Equity Association.

A 1928 movie featuring the first appearance of Mickey Mouse enters public domain on Jan. 1. But creative and commercial access to the character is complicated by both copyright and trademark law.

No injuries were reported following the weekend blaze at Disneyland, officials said. One visitor said Mickey Mouse vanished from the stage as soon as the dragon's head became engulfed in flames.
