It is an interesting year for that reason. Gregory Peck and Peter Finch both won Oscars for the two roles.
Arguably, the Daniels Finch is a subtly different characterization. A new lens. But then, the Cranston Beale dominated a production without a comparable weight afforded the Holden role in the film. (If you go back, and I did: it's Holden's story; one didn't quite feel that about Goldwyn, through no fault of the actor.) The two plays both re-minted their leading characters with new weight and focus. Still, a rare bit of a distinction, this horse race.
