• Lady of the Tropics (1939) - Robert Taylor, Joseph Schildkraut
• White Cargo (1942) - Walter Pidgeon, Frank Morgan, Richard Carlson, Reginald Owen

And also debuting on DVD is the three-disc George O'Brien Western Collection (1938) featuring nine of the cowboy star's RKO Westerns.

All of these will be available here at ClassicFlix on March 8th and add to the total of over 1,600 Warner Archive titles exclusively available for rent at ClassicFlix.com.
