Unbirthday film combines the idea of an unbirthday introduced in "Through the Looking-Glass" with the "Mad Tea Party" described in "Alice's Adventures in Wonderland". The unbirthday party is also the subject of a 1951 comic released to coincide with the film. The comic version is substantially longer (32 pages) than the scene in the animated film, and has Alice being invited to the unbirthday party of Tweedledum and Tweedledee (who are not actually present at the unbirthday party).
