Okay...I do not understand...at all...casting people who are in their 20s and 30s for these roles.

I gotta agree with Bingo. Hamill can work out, grow the beard maybe, that would work. Pass the torch for a new story. Nathan Fillion doesn't actually need to be Han Solo. This rebooty (yeah, rebooty) idea makes my skin crawl.

As for Star Trek, that was a full-up unapologetic reboot. In the midst of that I still don't think fans would have been good with an aged Spock played by Jeff Goldblum in pointy ears.

Just sayin'.
