The alternative names for Prince William and Prince Harry were Arthur and Albert.
As many parents do, Diana and Charles had alternative names for their sons. Arthur and Albert were a couple of them, but Diana didn’t want to use them.
However, these options became middle names. Her older son’s full name is William Arthur Philip Louis, and Harry’s is Henry Charles Albert David.
ARTHUR: The Lady of the Lake,...
...her arm clad in the purest shimmering samite, held aloft Excalibur from the bosom of the water signifying by Divine Providence that I, Arthur, was to carry Excalibur. And that is why I am your King.
DENNIS: Listen. Strange women lying in ponds distributing swords is no basis for a system of government. Supreme executive power derives from a mandate from the masses, not from some farcical aquatic ceremony.
ARTHUR: Be quiet!
DENNIS: Well, but you can't expect to wield supreme executive power just 'cause some watery tart threw a sword at you!
ARTHUR: Shut up!
DENNIS: I mean, if I went 'round saying I was an emperor just because some moistened bint had lobbed a scimitar at me, they'd put me away!
Got to watch the film again this evening...
