The question I have for the LJers: How old is Darth Vader at the end of Return of the Jedi?
I always assumed (without any real data) that the kids in Star Wars (Luke, Leia) were the age of the characters in George Lucas' previous film American Graffiti. That puts them roughly High School age. In Ep II, Anakin is clearly (to me) a teenager, and in Ep III he's a bit older but still "Young Skywalker". If Anakin is still a teen/young adult in III, that makes him in his late 30s in VI.
Did Darth Vader reach his 40th Birthday?
