I have just been experimenting with a program called 'File Juicer' which extracts text, video, audio, and picture files from larger packed files such as those found in 'Behind the Magic'.

Whilst searching through the text I came across this:

,"How did George Lucas derive R2-D2's name?","The name originated from the film term ""Reel 2, Dialogue 2.""","He simply repeated common phonetic sounds until he discovered one that he enjoyed.","He found the initials ""R2-D2"" on the back of a stereo system.","The license plate on his first car ended in ""R2D2.""","B. He simply repeated common phonetic sounds until he discovered one that he enjoyed.","In [The Making of the Empire Strikes Back], it is suggested that R2-D2's name was, in fact, derived from the film term ""Reel 2, Dialogue 2."" However, in [The Annotated Screenplays], Lucas corrected the tale and revealed that all of the characters' names were created phonetically to be pleasing to hear and easy to say.

Is this official word that 'The Making of the Empire strikes Back' was indeed released?
