The One Hunderd and One Dalmatians
When Mrs. Astor's buttler goes to get rid of the rest of the soufle, he throws it into a room full of dalmatians.

The "Westside Pipeway" where mutants spin dials to control the flow of sewage and avoid a catastrophic explosion, is a reference to a similar wall in Fritz Lang's silent film, Metropolis.
