Then there was the desire when casting Anakin in II & III to look like an older version of Jake, while also a younger version of Sebastian. I remember the article distinctly though Google isn't helping me locate it at the moment.
It was nuts when they actually changed out Sebastian Shaw at the end after making such a big to-do about casting Jake Lloyd to look like him. This was another case for Leo DiCaprio. Not only is he a better actor than Hayden, he actually looked like the previous actors to play the part.
