What is R2D2 an acronym for?
- Robot-squared Diagnostics-squared
- Resolution 2 Dependancy 2
- Robot 2 Development 2
- Reel 2 Dialogue 2
Though in the movies, R2D2 doesn't stand for anything, it definitely did come from somewhere. While working on American Graffiti with Walter Murch, George Lucas was asked if he could fetch 'R2D2' from the shelf. What Murch had been referring to was a designnated dialogue track titled Reel 2 Dialogue 2 and that is how the robot got its name. Source: A Brief Guide to Star Wars by Brian J. Robb
