Because of a studio dispute and copyright problems the Alan Ladd version has not been seen since it came and it was 1949 not 1947 in the US. You can find it on E-Bay available in England which is where I got it. Quality not top but still passable to watch.
Many thanks, Sabatini- or maybe Flynn-fan. I’m both.
My mother (who despised the Redford version) thought the only possibility for Jay other than Ladd was Steve McQueen, appealing but ambiguous.
