Asked how many wizards there are, Gandalf says there are five, naming himself, Saruman, and Radagast, then saying he can't remember the names of the other two, merely saying, "The two blues." Their names, Alatar and Pallando, appear in the book Unfinished Tales, a collection of J.R.R. Tolkien ideas and half-manuscripts edited into book form by his son Christopher Tolkien. The filmmakers didn't have rights to use material from that book, so the two blue wizards remain unnamed in the film.
