I, too, saw FINIAN'S RAINBOW in the theatre in its original roadshow form. Still have the souvenir booklet. My biggest problem with it is all too often Coppola breaks what had been a long-standing edict of Astaire's and does not always shoot him full-figure when he is dancing.
I happen to agree with Mr. Astaire and think there is nothing more pointless than a waist-high shot of a dancer. If you can't see their feet what's the point? In fact, if you can't see the entire body in movement what's the point? Cutting off intricate choreography for close-ups and medium shots is like watching widescreen in pan-and-scan. You're not seeing it as intended.
Of course, the big question about FINIAN'S RAINBOW...What the Hell ever happened to Don Francks? No one came on the scene or disappeared faster...
Though I haven't seen it in a long time, I remember liking BLOOD ON THE MOON a lot, thinking it a moody little western. And I love the title. I need another viewing to see how it stacks up with those other noir westerns PURSUED and, for my money, the best noir western, RAMROD, with Joel McCrea, Veronica Lake, and Don DeFore giving the best performance of his life.
