The top box-office picture of 1945 and the biggest hit in RKO history.
Interesting how the Oscar-winning director and the Oscar-winning star from the Oscar-winning Best Picture of 1944 move over to another studio to make the sequel to that picture.
The color in the poster image has the icky taint of TruColor by Consolidated.
And while I don't see Trigger, who may be off-camera feeding lines to the stars, that certainly looks like Roy Rogers in the priest's outfit, and, of course, Dale Evans in the nun's habit.
I'm guessing it's BELLS OF SAN ANGELO from 1947......
