Just now, Tramp Graphics said:I don’t think it is. Look at Obi Wan. GL went out of his way to cast an actor who was essentially a dead ringer for a young Alec Guinness. Not only does Ewan McGreggor look and sound like Alec Guinness, but they’re the exact same height (5’10”). He was perfectly cast. So it can be done. George Lucas was a stickler for such details. So yes, I have very high standards. But I also believe that those standards can be met.
Some of that comes down to luck.
