Query: WARNING

The DVD version of the film "The Hitch-Hiker" offered for sale by the Roan Group does not play on various DVD players. Roan is aware of this problem, but does not advertise it. I have (unfortunately) purchased two copies of this DVD and in each case, the DVD freezes after the first few seconds of the standard introductory warning.The film itself is an important noir by an important actress and director, Ida Lupino. It is well worth seeing, but buying it from the Roan Group will not necessarily give you the opportunity to view it. Buy it from KINO if you want to see it.
