Anakin's age
EP I - Anakin is 10
EP II - 10 Years later - Anakin is 20
EP III - 7 years later - Anakin is 27
EP IV - Twenty years later - Anakin is 47
EP V - Five years later - Anakin is 52
EP VI - A year or so later - Anakin is 53
I could buy, if Anakin had such a rough life that Shaw's Anakin was in his fifties, at least moreso than being 43...
