Murder on the Blackboard

Murder on the Blackboard is a 1934 American pre-Code mystery/comedy film starring Edna May Oliver as schoolteacher Hildegarde Withers and James Gleason as Police Inspector Oscar Piper. Together, they investigate a murder at Withers' school. It was based on the novel of the same name by Stuart Palmer. It features popular actor Bruce Cabot in one of his first post-King Kong roles, as well as Gertrude Michael, Regis Toomey, and Edgar Kennedy.

Murder on the Blackboard was the second of three films teaming Oliver and Gleason as Withers and Piper, following The Penguin Pool Murder and preceding Murder on a Honeymoon. Director George Archainbaud also directed the first film in the series.[1]
