Sony's Columbia Classics line debuts two more of the film noir mysteries in the Whistler series: The Voice of the Whistler (1945) and Mysterious Intruder (1946) on DVD for the first time.

Based on the popular radio program, actor Richard Dix starred in eight different Whistler films. The first film and its second sequel were put out by Sony last month. Sony's recent releases mark the first time any of the Whistler films have been available on DVD. Four more films remain unreleased and it's unknown how quick the studio will be to release the remaining films.

The Voice of the Whistler and Mysterious Intruder will be available here at ClassicFlix on June 16th. These new DVDs add to the total of over 250 Columbia Classics titles exclusively available for rent at ClassicFlix.com.
