An American Tail (1986)
"Ah yes, the animated mouse musical that taught me about immigration at the turn of the century. Pogroms, "no cats in America and the streets are paved with cheese" random Ellis Island name changes, the rise of social justice, suffrage, labor movements, and Tamanny Hall! "Are we men, or are we mice?!" "MICE""
Rik Mayall was a legend.
I also found out there are deleted scenes, including one were the Horned King's undead army murders his henchmen in a very disturbing and frightful way. The movie's a lot darker than any Disney film I know of.
