I Walk the Line (1970)

Synopsis
In this collaboration between actor Gregory Peck and director John Frankenheimer, Peck plays Southern sheriff Henry Tawes, who intends to bring moonshiner Carl McCain (Ralph Meeker) to justice. Instead, Tawes falls in love with McCain's nubile daughter, Alma (Tuesday Weld), and arranges for the feds to keep their hands off McCain's still. The sheriff thus risks completely destroying his work life and home life. Not surprisingly, Johnny Cash's "I Walk the Line" is heard on the soundtrack at various crucial junctures. ~ Hal Erickson, All Movie Guide
