Hitch-Hike (1978)
Superior thriller stars Franco Nero as a drunken hack writer, Corinne Clery as his rich wife, and David Hess (in one of his best film roles ever) as a bank robber looking for a way to escape the cops with a bag of money. When Hess hooks up with the unhappy couple, their vacation takes a vicious detour into murder and vengeance land.
Barely released here in the U.S., Hitch-Hike is one exploitation film every fan should see. Includes trailer, and interviews with stars Franco Nero, Corinne Clery, and David Hess. Now out of print DVD.
