I'm considering going back and re-doing the last volume. "Reboot Ralph" was released as "Wreck-it-Ralph", so that needs updated. Also, "King of the Elves" is still waiting to be released. I believe "Frozen" would need to be added to this collection as well. There are also more "future-proof" titles yet to be released (according to List of Disney theatrical animated features - DisneyWiki) that I could add. Unfortunately at this time, Disney will continue to churn out movies, yet I can only fit so many in the spine design. Any suggestions?
