Keeping track of all the "Game of Thrones" characters in the show can be difficult, but book readers have it way harder.
In the "Game of Thrones" TV series there are 553 listed cast members. That number includes uncredited roles, like "pit fight #1," but doesn't factor in extras.
Just above 500 is a pretty decent showing for a television show. But IBM researcher Vinith Misra fed supercomputer Watson the text from the original book series, "A Song of Ice and Fire" to get that tally count.
Watson counted 2,103 mentioned characters in the books.
Good luck keeping track of all those names.
