Game of Thrones

The character Joffrey Baratheon is modeled after the Roman emperor Caligula who was reputed to be extremely cruel and sadistic during his four-year reign.

In the year 2012, over 160 baby girls in the U.S. were legally named "Khaleesi", after the character in the show, although it is not the character's name (Daenerys) but a title.

Natural brunette, Emilia Clarke has stated that she has never dyed her hair for the show. Daenerys Targaryen's impressive blond locks are achieved via an elaborate wig and makeup system that takes considerable time to get into place.
