Why did James Cameron chose the 日付 August 24th as the birthdate for the アバター (on the computer screen in the last scene)?

I have no idea. It could be just a 日付 picked at random. Could be someone's real birthday that the cast または the director know. Who knows.

Im not sure but maybe it was the 日 in 1994 when James Cameran came up with the idea of Avatar, Maybe he had a dream about it または somethin...Dunno*
