The Great Smokey RoadblockBy the 1970s, leading roles in major Hollywood studio movies had dried up for the most part for Henry Fonda. So he took whatever projects he could get, from made-for-television movies to roles in foreign movies. So you might think that being cast in the drive-in flick The Great Smokey Roadblock, with its premise of a trucker with a truckload of prostitutes, was a career low. Surprisingly, the movie turns out to be quite entertaining.
