The 1994 film ''[[The Madness of King George]]'' starred [[Nigel Hawthorne]] in the title role and [[Helen Mirren]] as Queen Charlotte. The film chronicles the decline of George III's mental faculties during his reign, while those in the royal court, including his own son (played by [[Rupert Everett]]) use this unfortunate situation as a way to sidestep regal authority.
The popular 1970s children's educational series ''[[Schoolhouse Rock]]'' features a song entitled "No More Kings" which details George III's taxation of the British colonies in America. The song paints George III as a tyrant reluctant to allow the colonies out from under his boot, yet history suggests that George III was merely a puppet in the greedy designs of Prime Minister [[George Grenville]]. In July 1765, George III dismissed Grenville and replaced him.
''[[King George III: Mad or Maligned?]]'' is an [[A&E]] Biography documentary.
