The Lion, the Witch and the Wardrobe
From Tardis Wiki, the free Doctor Who reference
The Lion, the Witch and the Wardrobe was a book by C. S. Lewis. The Eleventh Doctor and Amy Pond inspired its creation by giving Lewis a copy of The Professor, the Queen and the Bookshop. (DWM: The Professor, the Queen and the Bookshop)
The Eighth Doctor referred to "happening upon wardrobe adventures", a central feature in the book's plot. (EDA: EarthWorld)
It is rumored that the next "Doctor Who" Christmas special will be a retelling of C.S. Lewis' novel.
