...The Bat (1959)

For a movie that runs a total of 80 minutes, The Bat flies awfully slow. Agnes Moorehead's performance as a mystery writer caught up in real-life murder is the only interesting aspect of this creaky tale based on the 1920 play by Mary Roberts Rinehart and Avery Hopwood. The original advertising campaign proclaimed that anyone who reveals the identity of the killer will answer to The Bat - ooooh, I'm scared.
