The Ace of Scotland Yard

The Ace of Scotland Yard is a 1929 Universal movie serial. It was the first partial sound serial released by Universal Pictures (although the 69th serial released, including the silent serials). Universal announced this as the first talking serial, but that title is generally agreed to belong to Mascot Pictures' The King of the Kongo (1929). It was released in both sound and silent versions. The serial is presumed to be lost.
