Uh...ok, even if you go the "replace Shaw with Hayden" route, you still run into the same problem. Now, Anakin looks like he did in Ep. 3, so rather than being twenty years too old, he's twenty years too young. Not exactly an improvement.

So unless you're going to suggest replacing Alec with Ewan, this observation won't work as a supporting argument for the Shaw replacement...

If you read my other post I believe I mentioned that GL should replace the current Hayden with a Hayden that looks older (meaning a different haircut, etc.) to try to match the age he is (which should be about 40-something).

Most 40 year olds still look sort of young, all he needs is an "older" haircut (not a pretty boy haricut LOL), and maybe some makeup to make him look older, but he still shouldn't look as old as Sebastian Shaw.
