What They've Got In Common: A British king who gives a speech! There's no stutter in Fable, though, so you'll have to import that weird kid Sunny from Metal Gear Solid 4 into your game. But then, THEN, you'll have...well, nothing that resembles the movie even remotely.
Fun Fact: Geoffrey Rush's character in The King's Speech, much like Jasper in Fable III, is actually voiced by John Cleese. No, seriously.
