Lady on a Train

This was the first Deanna Durbin film I've seen, and while it's much different than her other films, it seems a great place to start! The first thing that struck me was how likable Ms. Durbin is in the lead role. She keeps the tone light and airy, and the film flies along at a joyous speed! The photography is amazing (the snowy Manhattan sets and Ms. Durbin's close-ups are wonderful!) Deanna's vocals on "Night and Day" hint at a sensuality that wasn't present in her other pictures, and her rendition of "Silent Night" is divine.

I won't summarize the plot, as it has been done in other comments, just suffice to say that this hilarious whodunit is perfect viewing while curled up with a hot drink on a snowy winter evening!
