While I liked the film (not so much the score, which I considered largely sub-par, along the line of too many silent scores used with dvd re-issues), if one’s concern is “suitable for Catholic adults”, I suppose that it is notable that it involves a man leaving his presumptive wife (or lover?); which might have seemed scandalous in the era it is set. There is also a little profanity (you have to read lips) near the beginning, and one of the characters flips off another.
Cute film. Glad it was made. Not as good as Hugo, imo. I’d certainly recommend it, though!
