The 1951 film was based on two books by Lewis Carroll; name the sequel book.
Answer
Through the Looking-Glass
The 1951 film was based on two books by Lewis Carroll; the sequel book is Through the Looking-Glass.
Disney’s Alice in Wonderland draws primarily from Carroll’s Alice’s Adventures in Wonderland, published in 1865, while also incorporating characters, imagery, and ideas from its 1871 sequel, Through the Looking-Glass, and What Alice Found There. The film’s chess-like closing imagery especially reflects the sequel.
A common mix-up is treating Through the Looking-Glass as merely a modern sequel title. It is Carroll’s original second Alice book, not a continuation created for Disney. The two books have different structures: the first centers on Alice’s journey through Wonderland, while the second uses a chessboard journey and includes figures such as Tweedledum and Tweedledee, Humpty Dumpty, and the Red Queen.
