This is a fairly entertaining programmer featuring Robert Young in his early screen career. He is again teamed with Florence Rice, an up and coming actress who never quite made it in the big times, though she showed potential. Of interest is Ted Healy as Police Sergeant Magee (yes, another dumb detective/policeman role). Healy was the comic responsible for introducing The Three Stooges to the world. That may be a blessing or a curse depending on how much you like Moe, Larry, and Curly.
"The Longest Night" is a compact comedy thriller with the entire story taking place on one night (hence the title) at one location, a department store, except for the opening sequence which takes place on the street. Sidney Toler, in his pre-Charlie Chan days, has the meaty part of Captain Holt, the one in charge of the investigation when a murder occurs in the store. The cast includes an assortment of character actors including the often corny Olin Howland as a floorwalker.
Thought there is much attempt at humor, most of it is lame by today's standards. Many of the supposedly funny lines fall flat; even the slapstick seems forced. This film would have played better with less comedy and more thrills and chills.
Taken as a short murder mystery, "The Longest Night" works. Taken as a comedy, it falls on its tush.
