Ty Jr. is 50, is he not? I think he's too old to play his father at the time Ty Sr. had his affair with Garland. :) He's older now than his father lived to be. :( :( :(
It would have been great if they'd done a Tyrone Power biopic when Ty Jr. was in his 30s -- with the right makeup and lighting, he'd have been young enough to play the young TP and old enough to play the more mature TP too.
Based on seeing "Benjamin Button" yesterday, and the ability to make Brad Pitt like he was in his younger career, they could CGI Ty Jr. into a more youthful look.
Thanks to CGI, make-up may become more and more unecessary! Pretty eerie thought. Kind of computerized "Dorian Grey" effects.
