Ringo as Frodo?
No, Ringo as Gollum!
Thank God, they waited for Peter Jackson (even though he did some Grrrlpower re-writing of the real plot)! The casting of New Zealand as Middle Earth was brilliant! As was most of the casting.
The only real failure of Jackson was the deletion of the “Scouring of the Shire” sub-plot of LOTR; as anti-proggy/Leftist/collectivist, as any novel could get!
