It's all very well for GL to say -now- that all the stormtroopers in the other movies are clones, because it suits him to say that now and it ties in nicely with AOTC. But that doesn't mean that was what he was thinking when he first made Star Wars. In Star wars the stormtroopers are different heights and builds and have different voices, they don't all speak with New Zealand accents like the Clones do, as I pointed out before most of the clones would have been killed in the clone wars and there would be a big lapse in soldier numbers while they waited for more to be created; logically they would start recruiting civilians. In AOTC the officers are clones, in Star Wars they are all different people. When Luke and Han diguise themselves as Stormtroopers this would not work if the stormtroopers were clones as they would stand out due to their different heights and their voices; all clones are supposed to be exactly the same. It just doesn't make any sense for the Stormtroopers in the OT to be clones. Maybe some of them could be clones, fair enough, but not all of them...
