The road-tripping Phillips family, (Dana Andrews, Jeanne Crain, Laurie Mock and Tim Stafford) is pursued by irritated teen motorists, fleeing to the picnic grounds, in Hot Rods To Hell, 1967.
The source of Hot Rods To Hell was a 1956 Saturday Evening Post story. It was originally conceived as a TV movie but Hot Rods to Hell turned out to be too rough for that era's television so instead it went out to drive-in theatres across the country. John Brahm, a respected studio director of the forties (The Lodger, 1944), helmed this youth flick, though at this time he was better known for his television work. And as a concession to the older generation, the Phillips family was ingeniously cast with familiar faces from Hollywood's past: Dana Andrews of While the City Sleeps (1956) and Daisy Kenyon (1947) as well as Jeanne Crain of Cheaper By the Dozen (1950). These two had earlier co-starred in three films together, most notably 1945's State Fair. (source)
