King George and Rudyard...

... were buds? They visited each other, talked about motor cars and had whiskey together? I have been unable to confirm this. Also, in the very last scene in the film, a minor factual quibble: King George says he found his son's body (Prince John) still warm, even though the Prince died at a separate house from where the King was living at the time. The King would have had to journey to the other house to feel the boy's body, and I find it unlikely it would "still be warm" after the trip.
