I guess they're not counting the TV films that have been made about her.
I think Efron would look the part of young Tyrone adding dark contacts for his eyes. I liked him in Hairspray.
It's been discussed from time to time on the forum that George Cooney could be considered for a Ty biopic or portraying Ty for other reasons, though he's maturing and may be a bit old to play younger Ty.
And there's Ty's own son, too. Desi Arnaz, Jr., was in "The Mambo Kings" portraying his own father. Ty, Jr. could be considered.
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.
