Did You Know? Felix the Cat was animation's first star! He appeared in Feline Follies (1919) and even though he hadn't yet been given his name, he was a hit!. In that film and his second, Musical Mews, he was called "Master Tom". It was only in the third, Adventures of Felix (1919) that he received his permanent name — and his long, long career was off.
