Murder on the Blackboard is the second of three Hildegarde Withers stories that Edna May Oliver and James Gleason were teamed for. Today the charm of these two people, two of the best character actors that movies ever saw carry this rather dated and melodramatic story.
One of the teachers at Edna's school, Barbara Fritchie, winds up very dead and she's quite the lively corpse as the perpetrator keeps moving the body in an effort to be rid of it. In fact the only way the crime is discovered is because that day Edna kept young Jackie Searle after school.
Unlike the Thin Man movies where you could have as many as ten suspects or more in a room as Nick and Nora reveal all, this is not MGM with their lavish productions. This is RKO and this studio had a limited budget for their films. We only have four suspects so your chances of guessing who did it increase quite a bit.
Edgar Kennedy as the dumb cop who gets clunked on the head and develops amnesia is his usual funny self. In fact he's the foil used to catch the murderer in the end. As for the end, I found it a bit melodramatic for my taste and let it go at that.
But for fans of the wonderful Edna May Oliver and the dependable James Gleason this film is a must.
