I love this movie too.... The scene in Times Square with David Niven and Ginger Rogers is probably the most romantic one ever filmed (when they wish each other Happy New Year). Ronald Colman taught David Niven how to kiss his leading lady very well!
I agree it’s the best version, (with *David* Niven, not “Charles Niven”) as is typo-ed in the review. The musical version was the worst IMO.
